Docker image to perform a rclone sync based on a cron schedule, with healthchecks.io monitoring.

rclone is a command line program to sync files and directories to and from:

• Google Drive
• Amazon S3
• Openstack Swift / Rackspace cloud files / Memset Memstore
• Dropbox
• Google Cloud Storage
• Amazon Drive
• Microsoft OneDrive
• Hubic
• Backblaze B2
• Yandex Disk
• SFTP
• FTP
• HTTP
• The local filesystem

rclone needs a configuration file where credentials to access different storage provider are kept.

By default, this image uses a file /config/rclone.conf and a mounted volume may be used to keep that information persisted.

A first run of the container can help in the creation of the file, but feel free to manually create one.

$ mkdir config
$ docker run --rm -it -v $(pwd)/config:/config pfidr/rclone

A few environment variables allow you to customize the behavior of rclone:

• SYNC_SRC source location for rclone sync/copy/move command. Directories with spaces should be wrapped in single quotes.
• SYNC_DEST destination location for rclone sync/copy/move command. Directories with spaces should be wrapped in single quotes.
• SYNC_OPTS additional options for rclone sync/copy/move command. Defaults to -v
• SYNC_OPTS_EVAL further additional options for rclone sync/copy/move command. The variables and commands in the string are first interpolated like in a shell. The interpolated string is appended to SYNC_OPTS. That means '--backup-dir /old`date -I`' first evaluates to '--backup-dir /old2019-09-12', which is then appended to SYNC_OPTS. The evaluation happens immediately before rclone is called.
• SYNC_ONCE set variable to only run the sync one time and then exit the container
• RCLONE_CMD set variable to sync copy or move when running rclone. Defaults to sync
• RCLONE_DIR_CMD set variable to ls or lsf for source directory check style. Defaults to ls
• RCLONE_DIR_CMD_DEPTH set the limit of the recursion depth to this. Defaults to -1 (rclone default)
• RCLONE_DIR_CHECK_SKIP set variable to skip source directory check before sync. Use with caution
• CRON crontab schedule 0 0 * * * to perform sync every midnight. Also supprorts cron shortcuts: @yearly @monthly @weekly @daily @hourly
• CRON_ABORT crontab schedule 0 6 * * * to abort sync at 6am
• FORCE_SYNC set variable to perform a sync upon boot
• CHECK_URL healthchecks.io url or similar cron monitoring to perform a GET after a successful sync
• FAIL_URL Fail URL to perform a GET after unsuccessful execution. By default this is CHECK_URL with appended "/fail" at the end
• HC_LOG set variable to send log data to healthchecks.io. OUTPUT_LOG must also be set.
• OUTPUT_LOG set variable to output log file to /logs
• ROTATE_LOG set variable to delete logs older than specified days from /logs
• TZ set the timezone to use for the cron and log America/Chicago
• UID set variable to specify user to run rclone as. Must also use GID.
• GID set variable to specify group to run rclone as. Must also use UID.
• SUCCESS_CODES: set variable to a space-separated list of return codes that are considered successful. If the return code matches any of these codes, the response will be marked as a success. Example: SUCCESS_CODES="0 8 10". Default value is 0

When using UID/GID the config and/or logs directory must be writeable by this UID

$ docker run --rm -it -v $(pwd)/config:/config -v /path/to/source:/source -e SYNC_SRC="/source" -e SYNC_DEST="dest:path" -e TZ="America/Chicago" -e CRON="0 0 * * *" -e CRON_ABORT="0 6 * * *" -e FORCE_SYNC=1 -e CHECK_URL=https://hchk.io/hchk_uuid pfidr/rclone
