Version using docker-compose.yml?

[ms2d]

I have been trying to run this container from a docker-compose.yml file without success. It feels like I am close! But ultimately I get denied access over SSH.

Here is the file:

version: "3"
services:
  gitolite:
    image: jgiannuzzi/gitolite
    container_name: gitolite
    ports:
      - "22:22"
    environment:
      - SSH_KEY="$KEY"
      - SSH_KEY_NAME="$NAME"
    volumes:
      - gitolite-sshkeys:/etc/ssh/keys
      - gitolite-git:/var/lib/git
volumes:
  gitolite-sshkeys:
  gitolite-git:

$KEY and $NAME are replaced with the bash script:

KEY=$(cat ~/.ssh/id_rsa.pub) NAME=$(whoami) envsubst <docker-compose.ymt >docker-compose.yml

I am then denied access with the following error:

adam$ git clone git@localhost:gitolite-admin
Cloning into 'gitolite-admin'...
The authenticity of host 'localhost (::1)' can't be established.
ECDSA key fingerprint is SHA256:............
Are you sure you want to continue connecting (yes/no)? yes
Warning: Permanently added 'localhost' (ECDSA) to the list of known hosts.
git@localhost: Permission denied (publickey).
fatal: Could not read from remote repository.

Please make sure you have the correct access rights
and the repository exists.

Any ideas? Thanks!
