This guide is mainly based on Installer Gitlab en 5 minutes avec Docker
Create the docker volumes,
sudo mkdir -p /data/gitlab/{config,data,logs}/
Make sure 2222 or preferably 22, 80XX & 84XX ports are available,
netstat -antupe --inet --inet6 | grep LISTEN
Fetch/Update the community image and launch the container,
docker pull gitlab/gitlab-ce
app=gitlabprod
docker ps -a | grep $app
docker run -d --name $app --hostname $app --restart always \
-p 22XX:22 -p 80XX:80 -p 84XX:443 \
-v /data/gitlab/config:/etc/gitlab \
-v /data/gitlab/logs:/var/log/gitlab \
-v /data/gitlab/data:/var/opt/gitlab \
gitlab/gitlab-ce:latest
#gitlabprod.<datetag>.ready
docker ps -a | grep $app
docker logs $app
docker exec -ti $app bash
Note. if you wann force the resolution (it’s ok if DNS are right and resolve to the Docker host so I don’t use that),
--add-host="gitlab.example.com:127.0.0.1" --add-host="gitlab:127.0.0.1" \ --add-host="git.example.com:127.0.0.1" --add-host="git:127.0.0.1" \
Note. gitlab.example.com and gitlab should point to the docker host (assuming the DNS work) but just in case, you can also force the resolution inside the container. Also, in case you did not enable that and need to fix it afterwards into the container (may not be permanent and it may even be removed while the container is up and running, this is just a quick workaround),
vi /etc/hosts
127.0.0.1 gitlab.example.com gitlab 127.0.0.1 git.example.com git
This part is also discussed in the custom/ubuntu image guide.
Make the unix env nicer,
cat >> /etc/bash.bashrc <<-EOF export DEBIAN_FRONTEND=noninteractive export TERM=xterm alias cp='cp -i' alias mv='mv -i' alias rm='rm -i' alias ll='ls -alhF' alias runq='postfix flush' alias netstata='netstat -antpe --inet --inet6' EOF tail -20 /etc/bash.bashrc source /etc/bash.bashrc
Install missing packages for easy admin,
apt -y update
apt -y full-upgrade
apt -y install \
lsb-release \
nmap \
unzip \
curl \
iputils-ping \
net-tools \
netcat \
sudo \
telnet \
vim \
wget \
software-properties-common \
apt-transport-https \
less \
mlocate \
pwgen
OPTIONAL (sshd refuses password auth anyway) – Change the root password into the container, just in case,
pwgen passwd
MANDATORY – Setup git’s password,
pwgen passwd git
Handy symlink,
cd ~/ ln -s /etc/gitlab
Proceed with a standard postfix outgoing email setup for your container. Therefore, you don’t even have to tell GitLab to use an SMTP, it’s using the system MTA by default! See additional notes below if you really want to go for the hard way. Now that the MTA is setup, launch it so it also listens on port 25 locally,
rsyslogd postfix start
Specific mail aliases for Gitlab,
cd /etc/ cp -pi aliases alises.dist cat >> aliases <<-EOF root: user@example.com gitlab-www: root gitlab-redis: root gitlab-psql: root git: root EOF newaliases
Then also make sure the URL is right when providing links in the messages,
#don't change as it gets overridden by gitlab.rb cd /var/opt/gitlab/gitlab-rails/etc/ cp -pi gitlab.yml gitlab.yml.dist #don't change as it gets overridden by gitlab.rb cd /var/opt/gitlab/gitlab-shell/ cp -pi config.yml config.yml.dist cd /etc/gitlab/ cp -pi gitlab.rb gitlab.rb.dist vi gitlab.rb external_url 'https://gitlab.example.com/' #gitlab_rails['time_zone'] = 'Europe/Paris' gitlab_rails['gitlab_email_from'] = 'support@example.com' gitlab_rails['gitlab_email_display_name'] = 'Example Support' gitlab-ctl reconfigure netstat -antpe --inet --inet6 | grep LISTEN cd /var/opt/gitlab/gitlab-rails/etc/ diff -bu gitlab.yml.dist gitlab.yml cd /var/opt/gitlab/gitlab-shell/ diff -bu config.yml.dist config.yml
Setting up an Apache powered Reverse proxy
Point your browser to that URL,
https://gitlab.example.com/
If the thing resolves it may be time to re-commit your container to an image,
docker commit -p gitlabprod gitlabprod.`date +%s`.ready
Define the password for the gitlab root user. You can now login with,
root / <the password you just defined on the interface>
Further configure the app,
Admin area > Users > Edit Administrator account
name
email
Deploy your SSH keys,
(logo on the top right) > Profile Settings > (appears on the top menu) SSH Keys
Try to connect to the git unix user tru SSH, you should get a PTY error,
ssh git@gitlab.example.com ssh -p 2222 git@gitlab.example.com
If needed, watch the logs,
gitlab-ctl tail
Alternate outgoing-email method,
#cd /etc/gitlab/ #cp -pi gitlab.rb gitlab.rb.dist # #vi gitlab.rb #gitlab_rails['smtp_enable'] = true #gitlab_rails['smtp_address'] = "SMTP_SMARTHOST" #gitlab_rails['smtp_port'] = 25 #gitlab_rails['smtp_domain'] = "dockerhost.example.com or example.com, I don't know, maybe simply keep that one commented out" #gitlab_rails['smtp_authentication'] = plain #gitlab_rails['smtp_enable_starttls_auto'] = false # #gitlab-ctl reconfigure
