Before using this image you have to create the YAML configuration file /data/config.yml to be able to create users, provide global options and add shares. Here is an example:

auth:
  - user: foo
    group: foo
    uid: 1000
    gid: 1000
    password: bar
  - user: baz
    group: xxx
    uid: 1100
    gid: 1200
    password_file: /run/secrets/baz_password

global:
  - "force user = foo"
  - "force group = foo"

share:
  - name: foo
    path: /samba/foo
    browsable: yes
    readonly: no
    guestok: no
    validusers: foo
    writelist: foo
    veto: no
    hidefiles: /_*/
    recycle: yes

A more complete config.yml example is available here.

veto: no is a list of predefined files and directories that will not be visible or accessible:

/._*/.apdisk/.AppleDouble/.DS_Store/.TemporaryItems/.Trashes/desktop.ini/ehthumbs.db/Network Trash Folder/Temporary Items/Thumbs.db/

More info: https://www.samba.org/samba/docs/current/man-html/smb.conf.5.html#VETOFILES

hidefiles: /_*/ is a list of predefined files and directories that will not be visible, but are accessible:

/_*/

In this example, all files and directories beginning with an underscore (_) will be hidden.

More info: https://www.samba.org/samba/docs/current/man-html/smb.conf.5.html#HIDEFILES

recycle: yes this option enables vfs_recycle module. The vfs_recycle intercepts file deletion requests and moves the affected files to a temporary repository rather than deleting them immediately. This gives the same effect as the Recycle Bin on Windows computers.

More info: https://www.samba.org/samba/docs/current/man-html/vfs_recycle.8.html

Docker compose is the recommended way to run this image. Copy the content of folder examples/compose in /var/samba/ on your host for example. Edit the compose and configuration files with your preferences and run the following commands:

docker compose up -d
docker compose logs -f

You can also use the following minimal command:

docker run -d --network host \
  -v "$(pwd)/data:/data" \
  --name samba crazymax/samba

Recreate the container whenever I push an update:

docker compose pull
docker compose up -d

Values in a YAML file can be set by variables, and interpolated at runtime using a Bash-like syntax ${VARIABLE}.

Default values can be defined inline using typical shell syntax ${VARIABLE-default}. It evaluates to default only if VARIABLE is unset in the environment.

Here is an example:

auth:
  - user: foo
    group: foo
    uid: 1000
    gid: 1000
    password: bar

share:
  - name: foo
    path: /samba/foo
    browsable: ${BROWSABLE-no}
    readonly: no
    guestok: no
    validusers: foo
    writelist: foo

services:
  samba:
    image: crazymax/samba
    network_mode: host
    volumes:
      - "./data:/data"
      - "./foo:/samba/foo"
    environment:
      - "BROWSABLE=yes"
    restart: always

Use the following commands to check the logs and status:

docker compose logs samba
docker compose exec samba smbstatus

Service discovery for Windows can be enabled by setting WSDD2_ENABLE to 1.

You also need to set the following capabilities to the container:

• CAP_NET_ADMIN
• CAP_NET_RAW

Name will be the hostname of the host if network mode is host or one of the container. If you want to override this value, you can set hostname in your compose file or set WSDD2_HOSTNAME env var.

NetBIOS name will be the hostname of the host. If you want to override this value, you can set WSDD2_NETBIOS_NAME env var.

See examples/windows as an example.
