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.

ENVIRONMENT VARIABLES

CHARMAP - As above, configure character mapping
GLOBAL - As above, configure a global option
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
SMB - As above, disable SMB2 minimum version
TZ - Set a timezone, IE EST5EDT
USER - As above, setup a user
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.

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

Start an instance creating users and shares:

sudo docker run -it -p 139:139 -p 445:445 -d dperson/samba \
            -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"
