Running gitlab inside docker with certs from Let's Encrypt

This will serve SSH and HTTPS (with which I got an A+ from testssl).

Creates three docker containers:

gitlab-prostgres
gitlab-redis
gitlab, which is linked to the other two. This contains nginx, sshd, git, gitlab.

Volumes each have a volume mounted from the host system in /opt/docker-volumes/

Alter the various environment variables accordingly, mostly where they look like <this>

stfu and do it

mkdir -p /opt/docker-volumes/{gitlab/certs,gitlab-postgresql,gitlab-redis}

openssl dhparam -out /opt/docker-volumes/gitlab/certs/dhparam.pem 4096

./certbot-auto certonly --standalone -d <domain_name>

cp /etc/letsencrypt/live/<domain_name>/* /opt/docker-volumes/gitlab/certs/
mv /opt/docker-volumes/gitlab/certs/fullchain.pem /opt/docker-volumes/gitlab/certs/gitlab.crt
mv /opt/docker-volumes/gitlab/certs/privkey.pem /opt/docker-volumes/gitlab/certs/gitlab.key
mv /opt/docker-volumes/gitlab/certs/chain.pem /opt/docker-volumes/gitlab/certs/ca.crt
chmod 0400 /opt/docker-volumes/gitlab/certs/gitlab.key

^ I think these dirs need to be read/writable by uid 1000 on the host so you may need to do a chown 1000 -R /opt/docker-volumes/gitlab*

Then start things up:

postgresql

Choose a password for the gitlab database and replace into <db-password>

docker run --name gitlab-postgresql  -d \
    --restart always \
    --env 'DB_NAME=gitlabhq_production' \
    --env 'DB_USER=gitlab' \
    --env 'DB_PASS=<db-password>' \
    --env 'DB_EXTENSION=pg_trgm' \
    --volume /opt/docker-volumes/gitlab-postgresql:/var/lib/postgresql \
    sameersbn/postgresql:9.5-3

###redis

docker run --name gitlab-redis -d \
    --restart always \
    --volume /opt/docker-volumes/gitlab-redis:/var/lib/redis \
    sameersbn/redis:latest

###gitlab

Use the value you chose for <db-password> above.

Do this 3 times and record the output - used for GITLAB_SECRETS envs below.

pwgen -Bsv1 64

The GITLAB_ROOT_PASSWORD is kinda pointless I think but I feel cmore comfortable smashing something decent in there.

docker run --name gitlab -d \
  --restart always \
  --volume /opt/docker-volumes/gitlab:/home/git/data \
  --link gitlab-postgresql:postgresql \
  --link gitlab-redis:redisio \
  --publish 10022:22  \
  --publish 10443:443 \
  -e 'GITLAB_HTTPS=true' \
  -e 'GITLAB_SIGNUP_ENABLED=false' \
  -e 'GITLAB_PORT=10443' \
  -e 'GITLAB_SSH_PORT=10022' \
  -e 'GITLAB_ROOT_PASSWORD=<set_a_password>' \
  -e 'GITLAB_HOST=<domain_name>' \
  -e 'GITLAB_EMAIL=<email_address>' \
  -e 'DB_USER=gitlab' \
  -e 'DB_PASS=<db_password>' \
  -e 'DB_NAME=gitlabhq_production' \
  -e 'DB_TYPE=postgres' \
  -e 'SMTP_ENABLED=true' \
  -e 'SMTP_DOMAIN=<email_fqdn>' \
  -e 'SMTP_HOST=<smtp_server>' \
  -e 'SMTP_PORT=25' \
  -e 'SMTP_USER=<email_username>' \
  -e 'SMTP_PASS=<email_password>' \
  -e 'GITLAB_SECRETS_DB_KEY_BASE=<random-64-chars>' \
  -e 'GITLAB_SECRETS_SECRET_KEY_BASE=<random-64-chars>' \
  -e 'GITLAB_SECRETS_OTP_KEY_BASE=<random-64-chars>' \
  sameersbn/gitlab:8.14.3

Point your browser to http://<domain_name>:10443 and log in with the 'root' account password for initial setup.

autorenew let's encrypt certs

-To non-interactively renew all of your certificates, run "certbot-auto renew"

Use envs to speficy the location of the certs, remove needing to rename the certs
