Remote Control / API	Remote controlling rclone with its API

Remote controlling rclone with its API

If rclone is run with the --rc flag then it starts an HTTP server
which can be used to remote control rclone using its API.

You can either use the rclone rc command to access the API
or use HTTP directly.

If you just want to run a remote control then see the rcd command.

Supported parameters

--rc

Flag to start the http server listen on remote requests

--rc-addr=IP

IPaddress:Port or :Port to bind server to. (default "localhost:5572")

--rc-cert=KEY

SSL PEM key (concatenation of certificate and CA certificate)

--rc-client-ca=PATH

Client certificate authority to verify clients with

--rc-htpasswd=PATH

htpasswd file - if not provided no authentication is done

--rc-key=PATH

SSL PEM Private key

--rc-max-header-bytes=VALUE

Maximum size of request header (default 4096)

--rc-user=VALUE

User name for authentication.

--rc-pass=VALUE

Password for authentication.

--rc-realm=VALUE

Realm for authentication (default "rclone")

--rc-server-read-timeout=DURATION

Timeout for server reading data (default 1h0m0s)

--rc-server-write-timeout=DURATION

Timeout for server writing data (default 1h0m0s)

--rc-serve

Enable the serving of remote objects via the HTTP interface. This
means objects will be accessible at http://127.0.0.1:5572/ by default,
so you can browse to http://127.0.0.1:5572/ or http://127.0.0.1:5572/*
to see a listing of the remotes. Objects may be requested from
remotes using this syntax http://127.0.0.1:5572/[remote:path]/path/to/object

Default Off.

--rc-files /path/to/directory

Path to local files to serve on the HTTP server.

If this is set then rclone will serve the files in that directory. It
will also open the root in the web browser if specified. This is for
implementing browser based GUIs for rclone functions.

If --rc-user or --rc-pass is set then the URL that is opened will
have the authorization in the URL in the http://user:pass@localhost/
style.

Default Off.

--rc-enable-metrics

Enable OpenMetrics/Prometheus compatible endpoint at /metrics.

Default Off.

--rc-web-gui

Set this flag to serve the default web gui on the same port as rclone.

Default Off.

--rc-allow-origin

Set the allowed Access-Control-Allow-Origin for rc requests.

Can be used with --rc-web-gui if the rclone is running on different IP than the web-gui.

Default is IP address on which rc is running.

--rc-web-fetch-url

Set the URL to fetch the rclone-web-gui files from.

Default https://api.github.com/repos/rclone/rclone-webui-react/releases/latest.

--rc-web-gui-update

Set this flag to check and update rclone-webui-react from the rc-web-fetch-url.

Default Off.

--rc-web-gui-force-update

Set this flag to force update rclone-webui-react from the rc-web-fetch-url.

Default Off.

--rc-web-gui-no-open-browser

Set this flag to disable opening browser automatically when using web-gui.

Default Off.

--rc-job-expire-duration=DURATION

Expire finished async jobs older than DURATION (default 60s).

--rc-job-expire-interval=DURATION

Interval duration to check for expired async jobs (default 10s).

--rc-no-auth

By default rclone will require authorisation to have been set up on
the rc interface in order to use any methods which access any rclone
remotes. Eg operations/list is denied as it involved creating a
remote as is sync/copy.

If this is set then no authorisation will be required on the server to
use these methods. The alternative is to use --rc-user and
--rc-pass and use these credentials in the request.

Default Off.

Accessing the remote control via the rclone rc command

Rclone itself implements the remote control protocol in its rclone rc command.

You can use it like this

$ rclone rc rc/noop param1=one param2=two
{
	"param1": "one",
	"param2": "two"
}

Run rclone rc on its own to see the help for the installed remote
control commands.

JSON input

rclone rc also supports a --json flag which can be used to send
more complicated input parameters.

$ rclone rc --json '{ "p1": [1,"2",null,4], "p2": { "a":1, "b":2 } }' rc/noop
{
	"p1": [
		1,
		"2",
		null,
		4
	],
	"p2": {
		"a": 1,
		"b": 2
	}
}

If the parameter being passed is an object then it can be passed as a
JSON string rather than using the --json flag which simplifies the
command line.

rclone rc operations/list fs=/tmp remote=test opt='{"showHash": true}'

Rather than

rclone rc operations/list --json '{"fs": "/tmp", "remote": "test", "opt": {"showHash": true}}'

Special parameters

The rc interface supports some special parameters which apply to
all commands. These start with _ to show they are different.

Running asynchronous jobs with _async = true

Each rc call is classified as a job and it is assigned its own id. By default
jobs are executed immediately as they are created or synchronously.

If _async has a true value when supplied to an rc call then it will
return immediately with a job id and the task will be run in the
background. The job/status call can be used to get information of
the background job. The job can be queried for up to 1 minute after
it has finished.

It is recommended that potentially long running jobs, e.g. sync/sync,
sync/copy, sync/move, operations/purge are run with the _async
flag to avoid any potential problems with the HTTP request and
response timing out.

Starting a job with the _async flag:

$ rclone rc --json '{ "p1": [1,"2",null,4], "p2": { "a":1, "b":2 }, "_async": true }' rc/noop
{
	"jobid": 2
}

Query the status to see if the job has finished. For more information
on the meaning of these return parameters see the job/status call.

$ rclone rc --json '{ "jobid":2 }' job/status
{
	"duration": 0.000124163,
	"endTime": "2018-10-27T11:38:07.911245881+01:00",
	"error": "",
	"finished": true,
	"id": 2,
	"output": {
		"_async": true,
		"p1": [
			1,
			"2",
			null,
			4
		],
		"p2": {
			"a": 1,
			"b": 2
		}
	},
	"startTime": "2018-10-27T11:38:07.911121728+01:00",
	"success": true
}

job/list can be used to show the running or recently completed jobs

$ rclone rc job/list
{
	"jobids": [
		2
	]
}

Setting config flags with _config

If you wish to set config (the equivalent of the global flags) for the
duration of an rc call only then pass in the _config parameter.

This should be in the same format as the config key returned by
options/get.

For example, if you wished to run a sync with the --checksum
parameter, you would pass this parameter in your JSON blob.

"_config":{"CheckSum": true}

If using rclone rc this could be passed as

rclone rc operations/sync ... _config='{"CheckSum": true}'

Any config parameters you don't set will inherit the global defaults
which were set with command line flags or environment variables.

Note that it is possible to set some values as strings or integers -
see data types for more info. Here is an example
setting the equivalent of --buffer-size in string or integer format.

"_config":{"BufferSize": "42M"}
"_config":{"BufferSize": 44040192}

If you wish to check the _config assignment has worked properly then
calling options/local will show what the value got set to.

Assigning operations to groups with _group = value

Each rc call has its own stats group for tracking its metrics. By default
grouping is done by the composite group name from prefix job/ and id of the
job like so job/1.

If _group has a value then stats for that request will be grouped under that
value. This allows caller to group stats under their own name.

Stats for specific group can be accessed by passing group to core/stats:

$ rclone rc --json '{ "group": "job/1" }' core/stats
{
	"speed": 12345
	...
}

Data types

When the API returns types, these will mostly be straight forward
integer, string or boolean types.

However some of the types returned by the options/get
call and taken by the options/set calls as well as the
vfsOpt, mountOpt and the _config parameters.

• Duration - these are returned as an integer duration in
  nanoseconds. They may be set as an integer, or they may be set with
  time string, eg "5s". See the options section for
  more info.
• Size - these are returned as an integer number of bytes. They may
  be set as an integer or they may be set with a size suffix string,
  eg "10M". See the options section for more info.
• Enumerated type (such as CutoffMode, DumpFlags, LogLevel,
  VfsCacheMode - these will be returned as an integer and may be set
  as an integer but more conveniently they can be set as a string, eg
  "HARD" for CutoffMode or DEBUG for LogLevel.
• BandwidthSpec - this will be set and returned as a string, eg
  "1M".

Supported commands

{{< rem autogenerated start "- run make rcdocs - don't edit here" >}}

backend/command: Runs a backend command.

This takes the following parameters

• command - a string with the command name
• fs - a remote name string e.g. "drive:"
• arg - a list of arguments for the backend command
• opt - a map of string to string of options

Returns

• result - result from the backend command

For example

rclone rc backend/command command=noop fs=. -o echo=yes -o blue -a path1 -a path2

Returns

{
	"result": {
		"arg": [
			"path1",
			"path2"
		],
		"name": "noop",
		"opt": {
			"blue": "",
			"echo": "yes"
		}
	}
}

Note that this is the direct equivalent of using this "backend"
command:

rclone backend noop . -o echo=yes -o blue path1 path2

Note that arguments must be preceded by the "-a" flag

See the backend command for more information.

Authentication is required for this call.

cache/expire: Purge a remote from cache

Purge a remote from the cache backend. Supports either a directory or a file.
Params:

• remote = path to remote (required)
• withData = true/false to delete cached data (chunks) as well (optional)

Eg

rclone rc cache/expire remote=path/to/sub/folder/
rclone rc cache/expire remote=/ withData=true

cache/fetch: Fetch file chunks

Ensure the specified file chunks are cached on disk.

The chunks= parameter specifies the file chunks to check.
It takes a comma separated list of array slice indices.
The slice indices are similar to Python slices: start[:end]

start is the 0 based chunk number from the beginning of the file
to fetch inclusive. end is 0 based chunk number from the beginning
of the file to fetch exclusive.
Both values can be negative, in which case they count from the back
of the file. The value "-5:" represents the last 5 chunks of a file.

Some valid examples are:
":5,-5:" -> the first and last five chunks
"0,-2" -> the first and the second last chunk
"0:10" -> the first ten chunks

Any parameter with a key that starts with "file" can be used to
specify files to fetch, e.g.

rclone rc cache/fetch chunks=0 file=hello file2=home/goodbye

File names will automatically be encrypted when the a crypt remote
is used on top of the cache.

Authentication is required for this call.

core/bwlimit: Set the bandwidth limit.

This sets the bandwidth limit to the string passed in. This should be
a single bandwidth limit entry or a pair of upload:download bandwidth.

Eg

rclone rc core/bwlimit rate=off
{
    "bytesPerSecond": -1,
    "bytesPerSecondTx": -1,
    "bytesPerSecondRx": -1,
    "rate": "off"
}
rclone rc core/bwlimit rate=1M
{
    "bytesPerSecond": 1048576,
    "bytesPerSecondTx": 1048576,
    "bytesPerSecondRx": 1048576,
    "rate": "1M"
}
rclone rc core/bwlimit rate=1M:100k
{
    "bytesPerSecond": 1048576,
    "bytesPerSecondTx": 1048576,
    "bytesPerSecondRx": 131072,
    "rate": "1M"
}

If the rate parameter is not supplied then the bandwidth is queried

rclone rc core/bwlimit
{
    "bytesPerSecond": 1048576,
    "bytesPerSecondTx": 1048576,
    "bytesPerSecondRx": 1048576,
    "rate": "1M"
}

The format of the parameter is exactly the same as passed to --bwlimit

  • the COMBINED_OUTPUT will write the output to the "result" parameter

Returns

• result - result from the backend command
  • only set when using returnType "COMBINED_OUTPUT"
• error - set if rclone exits with an error code
• returnType - one of ("COMBINED_OUTPUT", "STREAM", "STREAM_ONLY_STDOUT", "STREAM_ONLY_STDERR")

For example

}

OR 
{
	"error": true,
	"result": "<Raw command line output>"
}

Authentication is required for this call.

returned.

Parameters

• group - name of the stats group (string)

Returns the following values:

{
	"speed": average speed in bytes/sec since start of the process,
	"bytes": total transferred bytes since the start of the process,
	"errors": number of errors,
	"fatalError": whether there has been at least one FatalError,

				"name": name of the file,
				"percentage": progress of the file transfer in percent,
				"speed": average speed over the whole transfer in bytes/sec,
				"speedAvg": current speed in bytes/sec as an exponentially weighted moving average,

• isBeta - boolean - true if this is a beta version
• os - OS in use as according to Go
• arch - cpu architecture in use according to Go
• goVersion - version of Go runtime in use

debug/set-block-profile-rate: Set runtime.SetBlockProfileRate for blocking profiling.

SetBlockProfileRate controls the fraction of goroutine blocking events
that are reported in the blocking profile. The profiler aims to sample
an average of one blocking event per rate nanoseconds spent blocked.

To include every blocking event in the profile, pass rate = 1. To turn
off profiling entirely, pass rate <= 0.

After calling this you can use this to see the blocking profile:

go tool pprof http://localhost:5572/debug/pprof/block

Parameters

• rate - int

debug/set-mutex-profile-fraction: Set runtime.SetMutexProfileFraction for mutex profiling.

SetMutexProfileFraction controls the fraction of mutex contention
events that are reported in the mutex profile. On average 1/rate
events are reported. The previous rate is returned.

To turn off profiling entirely, pass rate 0. To just read the current
rate, pass rate < 0. (For n>1 the details of sampling may change.)

Once this is set you can look use this to profile the mutex contention:

go tool pprof http://localhost:5572/debug/pprof/mutex

Parameters

• rate - int

Results

• previousRate - int

job/list: Lists the IDs of the running jobs

Parameters - None

vfs/forget: Forget files or directories in the directory cache.

This forgets the paths in the directory cache causing them to be
re-read from the remote when needed.

If no paths are passed in then it will forget all the paths in the
directory cache.

rclone rc vfs/forget

Otherwise pass files or dirs in as file=path or dir=path. Any
parameter key starting with file will forget that file and any
starting with dir will forget that dir, e.g.

rclone rc vfs/forget file=hello file2=goodbye dir=home/junk

This command takes an "fs" parameter. If this parameter is not
supplied and if there is only one VFS in use then that VFS will be
used. If there is more than one VFS in use then the "fs" parameter
must be supplied.

vfs/list: List active VFSes.

This lists the active VFSes.

It returns a list under the key "vfses" where the values are the VFS
names that could be passed to the other VFS commands in the "fs"
parameter.

vfs/poll-interval: Get the status or update the value of the poll-interval option.

Without any parameter given this returns the current status of the
poll-interval setting.

When the interval=duration parameter is set, the poll-interval value
is updated and the polling function is notified.
Setting interval=0 disables poll-interval.

rclone rc vfs/poll-interval interval=5m

The timeout=duration parameter can be used to specify a time to wait
for the current poll function to apply the new value.
If timeout is less or equal 0, which is the default, wait indefinitely.

The new poll-interval value will only be active when the timeout is
not reached.

If poll-interval is updated or disabled temporarily, some changes
might not get picked up by the polling function, depending on the
used remote.

This command takes an "fs" parameter. If this parameter is not
supplied and if there is only one VFS in use then that VFS will be
used. If there is more than one VFS in use then the "fs" parameter
must be supplied.

vfs/refresh: Refresh the directory cache.

This reads the directories for the specified paths and freshens the
directory cache.

If no paths are passed in then it will refresh the root directory.

rclone rc vfs/refresh

Otherwise pass directories in as dir=path. Any parameter key
starting with dir will refresh that directory, e.g.

rclone rc vfs/refresh dir=home/junk dir2=data/misc

If the parameter recursive=true is given the whole directory tree
will get refreshed. This refresh will use --fast-list if enabled.

This command takes an "fs" parameter. If this parameter is not
supplied and if there is only one VFS in use then that VFS will be
used. If there is more than one VFS in use then the "fs" parameter
must be supplied.

{{< rem autogenerated stop >}}

Accessing the remote control via HTTP

Rclone implements a simple HTTP based protocol.

Each endpoint takes an JSON object and returns a JSON object or an
error. The JSON objects are essentially a map of string names to
values.

All calls must made using POST.

The input objects can be supplied using URL parameters, POST
parameters or by supplying "Content-Type: application/json" and a JSON
blob in the body. There are examples of these below using curl.

The response will be a JSON blob in the body of the response. This is
formatted to be reasonably human readable.

Error returns

If an error occurs then there will be an HTTP error status (e.g. 500)
and the body of the response will contain a JSON encoded error object,
e.g.

{
    "error": "Expecting string value for key \"remote\" (was float64)",
    "input": {
        "fs": "/tmp",
        "remote": 3
    },
    "status": 400
    "path": "operations/rmdir",
}

The keys in the error response are

• error - error string
• input - the input parameters to the call
• status - the HTTP status code
• path - the path of the call

CORS

The sever implements basic CORS support and allows all origins for that.
The response to a preflight OPTIONS request will echo the requested "Access-Control-Request-Headers" back.

Using POST with URL parameters only

curl -X POST 'http://localhost:5572/rc/noop?potato=1&sausage=2'

Response

{
	"potato": "1",
	"sausage": "2"
}

Here is what an error response looks like:

curl -X POST 'http://localhost:5572/rc/error?potato=1&sausage=2'

{
	"error": "arbitrary error on input map[potato:1 sausage:2]",
	"input": {
		"potato": "1",
		"sausage": "2"
	}
}

Note that curl doesn't return errors to the shell unless you use the -f option

$ curl -f -X POST 'http://localhost:5572/rc/error?potato=1&sausage=2'
curl: (22) The requested URL returned error: 400 Bad Request
$ echo $?
22

Using POST with a form

curl --data "potato=1" --data "sausage=2" http://localhost:5572/rc/noop

Response

{
	"potato": "1",
	"sausage": "2"
}

Note that you can combine these with URL parameters too with the POST
parameters taking precedence.

curl --data "potato=1" --data "sausage=2" "http://localhost:5572/rc/noop?rutabaga=3&sausage=4"

Response

{
	"potato": "1",
	"rutabaga": "3",
	"sausage": "4"
}

Using POST with a JSON blob

curl -H "Content-Type: application/json" -X POST -d '{"potato":2,"sausage":1}' http://localhost:5572/rc/noop

response

{
	"password": "xyz",
	"username": "xyz"
}

This can be combined with URL parameters too if required. The JSON
blob takes precedence.

curl -H "Content-Type: application/json" -X POST -d '{"potato":2,"sausage":1}' 'http://localhost:5572/rc/noop?rutabaga=3&potato=4'

{
	"potato": 2,
	"rutabaga": "3",
	"sausage": 1
}

Debugging rclone with pprof

If you use the --rc flag this will also enable the use of the go
profiling tools on the same port.

To use these, first install go.

Debugging memory use

To profile rclone's memory use you can run:

go tool pprof -web http://localhost:5572/debug/pprof/heap

This should open a page in your browser showing what is using what
memory.

You can also use the -text flag to produce a textual summary

$ go tool pprof -text http://localhost:5572/debug/pprof/heap

Debugging go routine leaks

Memory leaks are most often caused by go routine leaks keeping memory
alive which should have been garbage collected.

See all active go routines using

curl http://localhost:5572/debug/pprof/goroutine?debug=1

Or go to http://localhost:5572/debug/pprof/goroutine?debug=1 in your browser.

Other profiles to look at

You can see a summary of profiles available at http://localhost:5572/debug/pprof/

Here is how to use some of them:

• Memory: go tool pprof http://localhost:5572/debug/pprof/heap
• Go routines: curl http://localhost:5572/debug/pprof/goroutine?debug=1
• 30-second CPU profile: go tool pprof http://localhost:5572/debug/pprof/profile
• 5-second execution trace: wget http://localhost:5572/debug/pprof/trace?seconds=5
• Goroutine blocking profile
  • Enable first with: rclone rc debug/set-block-profile-rate rate=1 (docs)
  • go tool pprof http://localhost:5572/debug/pprof/block
• Contended mutexes:
  • Enable first with: rclone rc debug/set-mutex-profile-fraction rate=1 (docs)
  • go tool pprof http://localhost:5572/debug/pprof/mutex

See the net/http/pprof docs
for more info on how to use the profiling and for a general overview
see the Go team's blog post on profiling go programs.

The profiling hook is zero overhead unless it is used.
