# Samba
Samba docker container
# What is Samba?
Since 1992, Samba has provided secure, stable and fast file and print services
for all clients using the SMB/CIFS protocol, such as all versions of DOS and
Windows, OS/2, Linux and many others.
# How to use this image
By default there are no shares configured, additional ones can be added.
## Hosting a Samba instance
sudo docker run -it -p 139:139 -p 445:445 -d dperson/samba -p
OR set local storage:
sudo docker run -it --name samba -p 139:139 -p 445:445 \
-v /path/to/directory:/mount \
-d dperson/samba -p
## Configuration
sudo docker run -it --rm dperson/samba -h
Usage: samba.sh [-opt] [command]
Options (fields in '[]' are optional, '<>' are required):
-h This help
-c "<from:to>" setup character mapping for file/directory names
required arg: "<from:to>" character mappings separated by ','
-g "<parameter>" Provide global option for smb.conf
required arg: "<parameter>" - IE: -g "log level = 2"
-i "<path>" Import smbpassword
required arg: "<path>" - full file path in container
-n Start the 'nmbd' daemon to advertise the shares
-p Set ownership and permissions on the shares
-r Disable recycle bin for shares
-S Disable SMB2 minimum version
-s "<name;/path>[;browse;readonly;guest;users;admins;writelist;comment]"
Configure a share
required arg: "<name>;</path>"
<name> is how it's called for clients
<path> path to share
NOTE: for the default values, just leave blank
[browsable] default:'yes' or 'no'
[readonly] default:'yes' or 'no'
[guest] allowed default:'yes' or 'no'
NOTE: for user lists below, usernames are separated by ','
[users] allowed default:'all' or list of allowed users
[admins] allowed default:'none' or list of admin users
[writelist] list of users that can write to a RO share
[comment] description of share
-u "<username;password>[;ID;group;GID]" Add a user
required arg: "<username>;<passwd>"
<username> for user
<password> for user
[ID] for user
[group] for user
[GID] for group
-w "<workgroup>" Configure the workgroup (domain) samba should use
required arg: "<workgroup>"
<workgroup> for samba
-W Allow access wide symbolic links
-I Add an include option at the end of the smb.conf
required arg: "<include file path>"
<include file path> in the container, e.g. a bind mount
The 'command' (if provided and valid) will be run instead of samba
ENVIRONMENT VARIABLES
* `CHARMAP` - As above, configure character mapping
* `GLOBAL` - As above, configure a global option (See NOTE3 below)
* `IMPORT` - As above, import a smbpassword file
* `NMBD` - As above, enable nmbd
* `PERMISSIONS` - As above, set file permissions on all shares
* `RECYCLE` - As above, disable recycle bin
* `SHARE` - As above, setup a share (See NOTE3 below)
* `SMB` - As above, disable SMB2 minimum version
* `TZ` - Set a timezone, IE `EST5EDT`
* `USER` - As above, setup a user (See NOTE3 below)
* `WIDELINKS` - As above, allow access wide symbolic links
* `WORKGROUP` - As above, set workgroup
* `USERID` - Set the UID for the samba server
* `GROUPID` - Set the GID for the samba server
* `INCLUDE` - As above, add a smb.conf include
**NOTE**: if you enable nmbd (via `-n` or the `NMBD` environment variable), you
will also want to expose port 137 and 138 with `-p 137:137/udp -p 138:138/udp`.
**NOTE2**: there are reports that `-n` and `NMBD` only work if you have the
container configured to use the hosts network stack.
**NOTE3**: optionally supports additional variables starting with the same name,
IE `SHARE` also will work for `SHARE2`, `SHARE3`... `SHAREx`, etc.
## Examples
Any of the commands can be run at creation with `docker run` or later with
`docker exec -it samba samba.sh` (as of version 1.3 of docker).
### Setting the Timezone
sudo docker run -it -e TZ=EST5EDT -p 139:139 -p 445:445 -d dperson/samba -p
### Start an instance creating users and shares:
sudo docker run -it -p 139:139 -p 445:445 -d dperson/samba -p \
-u "example1;badpass" \
-u "example2;badpass" \
-s "public;/share" \
-s "users;/srv;no;no;no;example1,example2" \
-s "example1 private share;/example1;no;no;no;example1" \
-s "example2 private share;/example2;no;no;no;example2"
# User Feedback
## Troubleshooting
* You get the error `Access is denied` (or similar) on the client and/or see
`change_to_user_internal: chdir_current_service() failed!` in the container
logs.
Add the `-p` option to the end of your options to the container, or set the
`PERMISSIONS` environment variable.
sudo docker run -it --name samba -p 139:139 -p 445:445 \
-v /path/to/directory:/mount \
-d dperson/samba -p
* High memory usage by samba. Multiple people have reported high memory usage
that's never freed by the samba processes. Recommended work around below:
Add the `-m 512m` option to docker run command, or `mem_limit:` in
docker_compose.yml files, IE:
sudo docker run -it --name samba -m 512m -p 139:139 -p 445:445 \
-v /path/to/directory:/mount \
-d dperson/samba -p
