<!-- 
Define secrets

    $(openssl rand -hex 16)
-->

Create APP

    dokku apps:create code

Setup Network & Domains

    dokku network:create cicd_net
    dokku network:set code attach-post-create cicd_net
    dokku config:set --no-restart code DOKKU_LETSENCRYPT_EMAIL=username@example.com
    
Setup Storage

    dokku storage:mount /etc/localtime:/etc/localtime:ro
    dokku storage:mount /etc/timezone:/etc/timezone:ro
    dokku storage:mount /home/data/code.forgejo/data:/data
    dokku storage:mount /home/git/.ssh/:/data/git/.ssh

Setup Configuration

    dokku config:set code
    DATABASE_URL:             mysql://xxxxx
    REDIS_URL:                redis://xxxxx
    USER_GID:                 1002
    USER_UID:                 1002


Deploy

    git remote add dokku dokku@example.com:code
    git push

## Create Wrapper

Add git user on host

    adduser --disabled-password git
    adduser git docker

Create ssh key for git user

    ssh-keygen -t rsa -f /home/git/.ssh/id_rsa -C "Forgejo Host Key"
    chmod 600 /home/git/.ssh/id_rsa

Create `/usr/local/bin/forgejo` with the following content

    FORGEJO_CID=code.web.1
    # FORGEJO_IP="$(docker inspect "$FORGEJO_CID" -f '{{ (index (index .NetworkSettings.Ports "80/tcp") 0).HostPort }}')"
    FORGEJO_IP="$(docker inspect "$FORGEJO_CID"  -f '{{ .NetworkSettings.IPAddress }}' 2>/dev/null )"

    ssh -T -p 22 -o StrictHostKeyChecking=no git@$FORGEJO_IP "SSH_ORIGINAL_COMMAND=\"$SSH_ORIGINAL_COMMAND\" $0 $@"

Success.
