This project is unmaintained. It was forked from asavartzeth/docker-sftp but receives no further love from either him nor me.
_See Configuration Options bellow, regarding $SFTP_DATADIR details (defaults to /data/sftp)
###Storing data in a host directory###
docker run --name some-sftp -v /path/container-data/sftp:/data/sftp -P -d asavartzeth/sftp
This is using the same principle as above. But instead of mounting the volume of another container you will mount a host directory.
This is useful in the sense that it could minimize filesystem overhead and would allow you to safekeep your data in a more traditional way. Another thing to note is, if you wish to use zfs, or another filesystem with no Docker backend, this enables a good compromise.
A possible downside to this approach might be lesser portability of your data.
##Exposing files & directories to the instance##
docker run --name some-sftp -v /path/dir:$SFTP_DATA_DIR/chroot/share/dir -P -d asavartzeth/sftp
Preferably you would do this when you first deploy the container. However, you could certainly do the deployment as instructed under "Deploying a simple sftp instance", commit and then re-deploy.
For information on the syntax of the openssh configuration files, see the official documentation.
If you wish to adapt the default configuration, use something like the following to copy it from a running container:
docker cp some-sftp:/etc/ssh/sshd_config /some/path
You can use the modified configuration with:
docker run --name some-sftp -v /some/path:/etc/ssh:ro -P -d asavartzeth/sftp
This is a full list of environment variables that will be used in the configuration of your instance.
SFTP_USER=...(defaults to sftp1)
SFTP_UID=...(defaults to 2001)
SFTP_PASS=...(defaults to randomly generated password)
SFTP_LOG_LEVEL=...(defaults to INFO)
The possible values are: QUIET, FATAL, ERROR, INFO, VERBOSE, DEBUG, DEBUG1, DEBUG2, and DEBUG3.
SFTP_DATA_DIR=...(defaults to /data/sftp)
This will set the location of a data volume. It is used by the runtime script, to enable the transfer of application data to an empty location. This location could be a data volume container, such as tianon/true, or a location on your host.
