Add a general-purpose authenticated SMB share alongside the existing Time Machine container, reusing the same patterns already in place.

Approach

Use dperson/samba (well-maintained, minimal image with full Samba + Avahi support)
network_mode: host — same as timemachine, required for mDNS/Avahi auto-discovery in Finder
Mount /home/padriano/share on the host into /share in the container
Provide a dedicated smb.conf at samba/smb.conf (new file, mirrors timemachine/smb.conf style)
Reuse the existing timemachine/avahi-daemon.conf (same interface, same settings)
New env vars in .env / .env.example: SAMBA_USERNAME, SAMBA_PASSWORD, SAMBA_UID, SAMBA_GID

Files to change

docker-compose.yml — add samba service
samba/smb.conf — new file, defines the [Share] section
.env.example — add new Samba env vars

New `samba` service (docker-compose.yml)

samba:
  image: dperson/samba:latest
  container_name: samba
  hostname: samba
  restart: unless-stopped
  network_mode: host
  environment:
    - USERID=${SAMBA_UID}
    - GROUPID=${SAMBA_GID}
    - TZ=${TZ}
  volumes:
    - /home/padriano/share:/share
    - /home/padriano/projects/composer/samba/smb.conf:/etc/samba/smb.conf:ro
    - /home/padriano/projects/composer/timemachine/avahi-daemon.conf:/etc/avahi/avahi-daemon.conf:ro

New `samba/smb.conf`

Mirrors the global section of timemachine/smb.conf (SMB2/3 only, Apple extensions via vfs fruit) but defines a [Share] section instead of [TimeMachine]:

[global]
  workgroup = WORKGROUP
  server role = standalone server
  security = user
  ntlm auth = no
  server min protocol = SMB2_10
  server max protocol = SMB3
  server signing = auto
  smb encrypt = desired
  load printers = no
  printing = bsd
  printcap name = /dev/null
  disable spoolss = yes
  vfs objects = catia fruit streams_xattr
  fruit:aapl = yes
  fruit:metadata = stream
  fruit:posix_rename = yes
  logging = file
  log file = /var/log/samba/log.%m
  max log size = 1000

[Share]
  path = /share
  browseable = yes
  read only = no
  create mask = 0664
  directory mask = 0775
  valid users = ${SAMBA_USERNAME}

`.env.example` additions

SAMBA_UID=1000
SAMBA_GID=1000
SAMBA_USERNAME=samba
SAMBA_PASSWORD=replace-with-your-samba-password

Mac client access

Once running, Mac Finder will auto-discover the share via mDNS. Manual connect: smb://samba.local/Share or smb://<host-ip>/Share.
