linux - Sharing /etc/passwd between two Docker containers -


i'm trying containerize application consists of 2 services defined. 1 basic server running on specific port , second 1 ssh server. first service creates users executing standard unix commands (managing user , ssh keys) , can login second ssh service. each service running in separate container , use docker compose make running together.

the issue i'm unable define docker volumes can user created first service can use second service. need share files /etc/passwd, /etc/shadow, /etc/group between both services.

what tried:

1) define volumes each file

  • not supported in docker compose (it can use directories volumes)

2) replace /etc/passwd symlink copy in volume

3) set whole /etc volume

  • doesn't work (only files image volume)
  • is ugly

i thrilled suggestion or workaround wouldn't require put both services in 1 container.
