Bulk Stash is an rclone
service to sync, or copy, files between different storage services. For example, you can copy files either to or from a remote storage services like Amazon S3 to Google Cloud Storage, or locally from your laptop to a remote storage. Bulk Stash is a dockerized version of rclone.
You can also use this for copying or syncing files locally to a remote SFTP server or between two remote SFTP servers.
There are advanced use cases where you can actually transfer a certain class of files (CSV) to Amazon S3 for import into Amazon Redshift, BigQuery or Amazon Athena. If you are interested in learning check out this blog post.
- Dockerized:
rclone
is neatly packed into a Docker image that can be run anywhere Docker can be installed. - Alpine Linux: The container uses Alpine Linux which makes it light and efficient. The image size is < 26mb.
- Environment Variables: The image is designed to take advantage of recent support in
rclone
to utilize environment variables. This means you don't have to step through the typical config initialization process. - Process Monitoring and Management: The container also uses
Monit
to ensure that long running processes are monitored under process management. For example,Monit
will make surecrond
is running in the background and will restart it if it crashed. You can extend Monit to monitor folders, check for file sizes and many other. - Configuration: Configuration can be stored and managed outside the container. Configurations can also be inserted at runtime manually or via a controller script/app
- Runtime: You can run a collection of containers running independent tasks via config files. This means you can wrap the Docker service with other apps like bash, python and so forth on your host
- Deployment: You can setup things like Amazon Lambda and ECS tasks to control the runtime tasks. Configurations can be encrypted and stored in a service like AWS KMS. Configuration attributes can then be provided by an end user via a front-end web app. For example, you can have a form that collects all the S3 or Google OAuth tokens. A front end is not include :)
- Notifications: You can uses services like cronalarm, Cronitor.io, healthchecks.io...to set status and alerts. Notifications via Slack, Hipchat... are also possible, but not enabled.
- Folder Size Monitoring: Local source folders can be monitored. If the size of the contents in the source folder exceed a value you set an rclone copy operation will occur
- MD5/SHA1 hashes checked at all times for file integrity
- Timestamps preserved on files
- Partial syncs supported on a whole file basis
- Copy mode to just copy new/changed files
- Sync (one way) mode to make a directory identical
- Check mode to check for file hash equality
- Can sync to and from network, eg two different cloud accounts
- Optional encryption (Crypt)
- Optional FUSE mount (rclone mount)
- Optional database loading
What services are supported?
- Google drive
- Amazon S3
- Swift / Rackspace Cloudfiles / Memset Memstore
- Dropbox
- Google Cloud Storage
- Local filesystem

- Backblaze B2
- Hubic
- Microsoft OneDrive

For the items in bold there are sample commands and configurations in the readme.
First, pull the latest docker image:
docker pull openbridge/ob_bulkstash
This will pull the latest version by default. However, as part of the hooks/build
process we publish a number of older versions of rclone. If you want to see the available versions, check out Docker Hub openbridge/ob_bulkstash
. For example, if you wanted to run version 1.47
, then pull that version like this:
docker pull openbridge/ob_bulkstash:1.47.0
Additional pre-built versions are tagged and available for use: https://hub.docker.com/r/openbridge/ob_bulkstash/tags/
If you want to build your own image, you need to pass the version you want to use:
docker build --build-arg RCLONE_VERSION=1.47.0 -t openbridge/ob_bulkstash:1.46 .
docker build --build-arg RCLONE_VERSION=1.47.0 -t openbridge/ob_bulkstash:latest .
Got your version setup? Great. Next, we need to define a configuration for remote storage locations. The following demonstrates how to sync Amazon and Google cloud storages.
The validate that your build worked correctly, you can run a simple check which will have rclone echo the version back to you.
If you run this docker run openbridge/ob_bulkstash rclone -V
you should see the version displayed like this:
rclone v1.47.0
- os/arch: linux/amd64
- go version: go1.12.4
If you see this, success! Your image is ready to go!
In our example we have a source of files at Amazon S3 and destination for those files at Google Cloud Storage location. This means we will need to set the configuration ENV variables for source and destination.
Here is an Amazon Simple Storage Service (aka "S3") config:
RCLONE_CONFIG_MYS3_TYPE=s3
RCLONE_CONFIG_MYS3_ACCESS_KEY_ID=enter your access key
RCLONE_CONFIG_MYS3_SECRET_ACCESS_KEY=enter your secret key
RCLONE_CONFIG_MYS3_SERVER_SIDE_ENCRYPTION=AES256
RCLONE_CONFIG_MYS3_STORAGE_CLASS=REDUCED_REDUNDANCY
The first thing is to define the type
as s3: RCLONE_CONFIG_MYS3_TYPE=s3
Next, you need to provide credentials to access (pull data from or copy data to) S3:
RCLONE_CONFIG_MYS3_ACCESS_KEY_ID=enter your access key
and
RCLONE_CONFIG_MYS3_SECRET_ACCESS_KEY=enter your secret key
You will want to set the encryption for the data you send to S3: RCLONE_CONFIG_MYS3_SERVER_SIDE_ENCRYPTION=AES256
You can also set your storage class in the event you want to use lower cost options: RCLONE_CONFIG_MYS3_STORAGE_CLASS=REDUCED_REDUNDANCY
. Set this to your preference.
Like S3 we can use Google Cloud Storage as a remote location.
RCLONE_CONFIG_MYGS_TYPE=google cloud storage
RCLONE_CONFIG_MYGS_CLIENT_ID=
RCLONE_CONFIG_MYGS_CLIENT_SECRET=
RCLONE_CONFIG_MYGS_PROJECT_NUMBER=foo-mighty-139217
RCLONE_CONFIG_MYGS_SERVICE_ACCOUNT_FILE=/auth.json
The first step is to set the type
for Google: RCLONE_CONFIG_MYGS_TYPE=google cloud storage
Next, make sure you set your credentials like you did for S3: RCLONE_CONFIG_MYGS_CLIENT_ID=enter your client key
and RCLONE_CONFIG_MYGS_CLIENT_SECRET=enter your secret key
The project number is only needed only for list/create/delete buckets:
RCLONE_CONFIG_MYGS_PROJECT_NUMBER=foo-mighty-139217
If you are using a Google Account Credentials JSON file you would leave the client ID and secret blank and enter the path to your file:
RCLONE_CONFIG_MYGS_SERVICE_ACCOUNT_FILE=/auth.json
You will need to make sure that the volume that contains the auth file is mounted and the path is passed via RCLONE_CONFIG_MYGS_SERVICE_ACCOUNT_FILE
.
Thats it! You defined two remote locations, one for Amazon and one for Google. You can start to transfer files.
With your config setup, now you can run rclone
!
This is an example Docker RUN
command
docker run openbridge/ob_bulkstash \
--env-file env/sample.env \
rclone copy MYS3:myawsbucket/path/to/file/ MYGS:mygooglebucket/path/to/files/
Check out the docker run docs for the latest syntax.
Lastly, you can use Docker Compose:
docker-compose up -d
or
/usr/local/bin/docker-compose -f prod.yml up -d --remove-orphans
Note: You will need to put the appropriate command in the compose YAML file you want docker rclone to run.
These are a couple of simple examples around wrapping the Docker image with Bash on your host.
This example will go through all the env files and run the image with a COPY
command:
for i in ./env/*.env; do
docker run -v /my/volume:/data -it --env-file ${i} openbridge/ob_bulkstash rclone copy MYS3:myawsbucket/path/to/file/ MYGS:mygooglebucket/path/to/files/
done
Earlier we showed a simple rclone command to echo the version number:
docker run openbridge/ob_bulkstash rclone -V
Here is an example that mounts the Google auth file needed for service level accounts:
for i in ./env/prod/*.env; do
echo "working on $i"
bash -c "docker run -it -v /auth/prod/auth.json:/auth.json --env-file ${i} openbridge/ob_bulkstash rclone copy MYS3:myawsbucket/path/to/file/ MYGS:mygooglebucket/path/to/files/"
if [[ $? = 0 ]]; then echo "OK: "; else echo "ERROR: "; fi
done
If you want to persist your container you can set it up to always be running with crond
as a background process. While most everything is automated there are a few configuration items you need to set.
IMPORTANT: This assumes you have a basic understanding of Docker and background processes. If you do not know what --detach , -d
means then please review the Docker docs about running in detached mode (hint: this is how you run things in the background)
Depending on your use of CROND
, it may not have access to the OS defined ENV
variables. As a convenience, the image will output these to a file:
printenv | sed 's/^\([a-zA-Z0-9_]*\)=\(.*\)$/export \1="\2"/g' | grep -E "^export RCLONE" > /cron/rclone.env
If needed, you can then import these variables into any scripts that you want to run in the container such as using something like source /cron/rclone.env
.
Running crond
requires a proper configuration file. You can easily add a crontab config file and have the container use it. A crontab.conf
should look something like this:
SHELL=/bin/bash
PATH=/usr/local/sbin:/usr/local/bin:/usr/sbin:/usr/bin:/sbin:/bin
*/15 * * * * /usr/bin/env bash -c /rclone.sh run 2>&1
There is a sample of this in cron/crontab.conf
. You can use this as a starting point for your own config. Once you have your config ready, we can move to Step 2.
Next, you will want to mount your config file. The config is on your host, not in the container. To get it into your container you need to mount it from your host into the container.
The basic template is this:
-v /path/to/the/file/on/your/host/crontab.conf:/where/we/mount/in/container/crontab.conf
This example shows the mount your config in docker compose format:
volumes:
- /Github/ob_bulkstash/cron/crontab.conf:/cron/crontab.conf
It will look the same if you are doing it via Docker run:
-v /Github/ob_bulkstash/cron/crontab.conf:/cron/crontab.conf
In those examples, the crontab.conf
located in my local GitHub folder will get mounted inside the container at /cron/crontab.conf
Mounting your config makes it available to the startup service within your container. If you are unfamiliar with -v
or volumes
, check the docs from Docker.
In your ENV
make sure to set the path to the location you are mounting your crontab.conf
file. In our example above we are using /cron/crontab.conf
. This means you set the ENV
path like this:
RCLONE_CRONFILE=/cron/crontab.conf
This is the location in your container, not the host
You can let the image generate and run a command for you under CROND
.
This is geared to running a single CROND
task. If you want to run multiple tasks, it is best to choose Option 1 which allows you more control over the number of tasks run.
In your ENV, you need to set the desired command via RCLONE_SYNC_COMMAND
. Here is an example command:
docker run -d -e RCLONE_SYNC_COMMAND="*/15 * * * * /usr/bin/env bash -c /foo run" openbridge/ob_bulkstash crond -f
This will result in your container running in the detached mode (in the background) with a CROND
entry like this:
SHELL=/bin/bash
PATH=/usr/local/sbin:/usr/local/bin:/usr/sbin:/usr/bin:/sbin:/bin
*/15 * * * * /usr/bin/env bash -c /foo run
This is just an example command, it will likely vary according to what you are looking too run.
Please note that if you set your own crontab config file via RCLONE_CRONFILE=/cron/crontab.conf
it will take precedent over anything you pass via -e
or set other environment variables.
Here are a few examples of running Docker and CROND
in the background. You can accomplish the same using docker-compose
Running in detached mode:
docker run -d -e RCLONE_SYNC_COMMAND="*/15 * * * * /usr/bin/env bash -c /foo run" openbridge/ob_bulkstash crond -f
You can see the process running in the background:
PID PPID USER STAT VSZ %VSZ CPU %CPU COMMAND
31 0 root R 1528 0% 3 0% top
1 0 root S 1516 0% 1 0% crond -f
Running in detached mode using the rcron.sh
helper script. This will use Monit has the background process monitor to make sure CROND
is always running:
docker run -d -e RCLONE_SYNC_COMMAND="*/15 * * * * /usr/bin/env bash -c /foo run" openbridge/ob_bulkstash rcron start
You can see the process running in the background:
PID PPID USER STAT VSZ %VSZ CPU %CPU COMMAND
21 1 root S 4788 0% 2 0% monit -Iv -c /etc/monitrc -l /dev/null
1 0 root S 2172 0% 3 0% bash /usr/bin/rcron start
23 0 root R 1524 0% 2 0% top
20 1 root S 1516 0% 0 0% crond -b
Here is another example running Monit as the controlling process:
docker run -d -e RCLONE_SYNC_COMMAND="*/15 * * * * /usr/bin/env bash -c /foo" openbridge/ob_bulkstash monit -Iv -c /etc/monitrc -l /dev/null
You can see the process running in the background:
PID PPID USER STAT VSZ %VSZ CPU %CPU COMMAND
1 0 root S 4788 0% 2 0% monit -Iv -c /etc/monitrc -l /dev/null
22 0 root R 1528 0% 1 0% top
21 1 root S 1516 0% 3 0% crond -b
Hopefully you get the point on how to do this. You have options, just make sure you understand the basics on how to run Docker in various contexts.
Included in the image is a utility script. You can use this as a robust example for creating your own. It highlights the potential to mount scripts like this into your container to run different types of operations.
Note: rclone.sh
is provided as-is and has not been fully tested. Think of it as a proof-of-concept, not something you should blindly use.
The script shows an example of how to run rclone copy
and rclone move
. It will also has a foldersize
check in the event you want to trigger a rclone move
. How is this helpful? If your disk is getting full this can trigger what amounts to be a cleanup task.
While the image contains rclone.sh
, you will likely want to mount your own version of the script. For example;
-v /path/to/the/file/on/your/host/script.sh:/path/in/container/script.sh
Also, you need to make sure the image can use /rclone.sh
. This means you need to make sure any required environment variables are set correctly. For example, in your ENV
, you need to set the following for rclone.sh
:
RCLONE_CROND_SCHEDULE
crontab schedule* * * * *
to perform sync every midnightRCLONE_CROND_SOURCE_PATH
source location forrclone copy
commandRCLONE_CROND_DESTINATION_PATH
destination location forrclone copy
command
In your environment file you need to make sure your source and destination remotes are set. You need to put the full statement (remote names, buckets, paths...) for the source and destination for each variable.
RCLONE_CROND_SOURCE_PATH="/temp"
RCLONE_CROND_DESTINATION_PATH="MYS3:myawsbucket/path/to/file/"
This will ensure that rclone
knows where to look for the files and where you want them delivered.
This is what it would look like in your config:
RCLONE_CROND_SCHEDULE=*/5 * * * *
RCLONE_CROND_SOURCE_PATH="/tmp"
RCLONE_CROND_DESTINATION_PATH="MYS3:ob-testing/ebs"
RCLONE_CROND_HEALTHCHECK_URL
If you want to use a cron healthcheck service, set the environment variable:
RCLONE_CROND_HEALTHCHECK_URL
used for health check services to ping status like cronalarm, Cronitor.io, healthchecks.io...
This is what it would look like in your config:
RCLONE_CROND_SCHEDULE=*/5 * * * *
RCLONE_CROND_SOURCE_PATH="/tmp"
RCLONE_CROND_DESTINATION_PATH="MYS3:ob-testing/ebs"
RCLONE_CROND_HEALTHCHECK_URL=https://hchk.io/asads-aa12-ee23-qqw1-543e4c2ddv54385
You can use a foldersize
check to monitor your source path. To do this set the environment variable RCLONE_CROND_SOURCE_SIZE
to a number in megabytes. For example, if you want to monitor your source path for 1 GB of files, you would set RCLONE_CROND_SOURCE_SIZE=1000
. The 1000 megabytes = 1 GB.
RCLONE_CROND_SCHEDULE=*/5 * * * *
RCLONE_CROND_SOURCE_PATH="/tmp"
RCLONE_CROND_DESTINATION_PATH="MYS3:ob-testing/ebs"
RCLONE_CROND_SOURCE_SIZE="1000"
You can setup SFTP remotes. This allows you to upload or download files from an SFTP server. You can also do server to server transfers between two remotes.
Lastly, if you want to pipeline data to Redshift, BigQuery, Athena or Spectrum via rclone take a look at the following batch data pipeline workflow:
If you have any questions about how to pipeline data to a warehouse let me know.
Sample config
RCLONE_CONFIG_MYSFTP_TYPE=sftp
RCLONE_CONFIG_MYSFTP_HOST=pipeline.openbridge.io
RCLONE_CONFIG_MYSFTP_USER=user
RCLONE_CONFIG_MYSFTP_PORT=443
RCLONE_CONFIG_MYSFTP_PASS=34232424234234234
Here is a sample command that copies data from a remote SFTP server locally with a 60s
timeout:
rclone copy sftp:/folder /tmp --contimeout 60s
Here are a few sample commands you can use use for testing or general usage
List a remote drive like this: rclone lsd {remote name}:
Note: The command has :
at the after the remote. If you do not include :
things wont work
Replace {remote name}
with your actual remote name. Using our Amazon example it would look like this
rclone lsd MYS3:
Using Docker this is a possible way to run the command:
docker run -env-file /env/my.env openbridge/ob_bulkstash rclone lsd MYS3:
This will output your remote buckets like this:
-1 2017-04-11 16:38:05 -1 athena-lambda
-1 2016-12-04 14:32:54 -1 aws-athena-query
-1 2016-12-17 14:19:23 -1 aws-logs
-1 2015-03-31 21:48:40 -1 cf-templates
-1 2016-11-17 15:56:56 -1 chat000
-1 2016-10-06 17:09:10 -1 chat001
-1 2016-10-24 05:28:09 -1 chat002
-1 2014-02-11 14:55:25 -1 prod001
-1 2014-02-11 14:55:43 -1 prod002
-1 2016-06-05 21:59:28 -1 temp002
List remote files of a certain type:
rclone --include "*.jpg" ls {remote name}:{aws bucket name}/{folder}
Using our AWS remote:
rclone --include "*.jpg" ls MYS3:mybucket/files
Make a new bucket sample:
rclone mkdir {remote name}:{aws bucket name}
Using our AWS remote:
rclone mkdir MYS3:mynewbucket
Sync file sample:
rclone sync /home/local/directory {remote name}:{aws bucket name}/{folder}
Using our AWS remote:
rclone sync /tmp MYS3:mynewbucket/temp [--drive-use-trash]
The basic structure of the rclone
command looks like this for COPY
:
rclone copy {{source_config}}:{{bucket}}/{{path/to/file/}} {{dest_config}}:{{bucket}}/{{path/to/file/}}
You assign your source and destinations according to your configs. For example, in this case we have MYS3
and MYGS
where we assing one as the source and the other as the destination:
rclone copy MYS3:myawsbucket/path/to/file/ MYGS:mygooglebucket/path/to/files/
This docker image uses rclone and is focused on separating configuration from the runtime. This does not preclude using a traditional config file. Feel free to go down that path if it makes sense to you. The image would support it.
- Each config statement has
RCLONE_
. It is the prefix for each variable. - In each variable you define the name you block by setting
RCLONE_CONFIG_{{NAME}}_
. In our S3 example we useRCLONE_CONFIG_MYS3
for Amazon andRCLONE_CONFIG_MYGS
for Google. - The last part is the formal configuration attribute. For example,
TYPE
,ACCESS_KEY_ID
orSERVER_SIDE_ENCRYPTION
are standard config elements for s3 rclone. Normally be prefixed like this:--type
- You need to make sure
{{NAME}}
is unique to avoid any collisions in your configs. For example, you cant have multipleRCLONE_CONFIG_MYS3
statements. If you have multiple S3 locations do something likeRCLONE_CONFIG_MYS3-01
,RCLONE_CONFIG_MYS3-02
andRCLONE_CONFIG_MYS3-03
Environment variables can be formed to point at the content of Docker secrets
files, so as to avoid giving away sensitive information. Any environment
variable which value looks like the following DOCKER-SECRET::<path>
(note the
leading DOCKER-SECRET
keyword and the double colon ::
) will be replaced by
the content of the file at <path>
if it exists. Relative paths are
automatically resolved to /run/secrets
(the default path for Docker secrets),
but absolute paths can also be used.
These tips come from http://moo.nac.uci.edu/~hjm/HOWTO-rclone-to-Gdrive.html
To obtain good transfer rates, you have to increase the number and size of files you transfer at one time, as well as the number of simultaneous streams and the checkers. So, for rclone to transfer files efficiently, there has to be a large payload per transfer and a number of simultaneous streams. It works best if there are large, identically sized files, but regardless, larger files are better, because of the initiation overhead.
rclone --transfers=32 --checkers=16 --drive-chunk-size=16384k \ --drive-upload-cutoff=16384k copy /my/folder MYGS:mybucket/myfiles
Copy files from remote location locally:
rclone --transfers=12 copy MYGS:mybucket/myfiles /my/local/dir
