Docker-Gitlab-AutoDeploy

CI/CD using docker and Gitlab repository

Update Docker Compose file

update file docker-compose.autodeploy.yml
change : registry.gitlab.com/{GITLAB_USERNAME}/{PROJECT_NAME}:latest

GITLAB_USERNAME = change with your gitlab username
PROJECT_NAME = change with your project name
Example : registry.gitlab.com/annasblackhat/gitlab_ci_cd:latest

Server Config

On your server, please make sure you have installed docker-compose

sudo apt-get update
sudo apt-get -y install python-pip
sudo pip install docker-compose

then we will create ssh key so then Gitlab can deploy new docker image to our server

• Create the .ssh directory if you don't have one

mkdir ~/.ssh
chmod 700 ~/.ssh

• Create SSH key pair

ssh-keygen -t rsa

• Display the public key, and copy to new file named ~/.ssh/authorized_keys

cat ~/.ssh/id_rsa.pub
nano ~/.ssh/authorized_keys
chmod 600 ~/.ssh/authorized_keys

• Copy the private key, save it, we will use it to create global variable in Gitlab. To show the private key using cat

cat ~/.ssh/id_rsa

• Go to your Gitlab, and navigate to Setting > CI/CD and scroll to Environment variables and create these variables :

DEPLOYMENT_SERVER_IP=your_ip_address
DEPLOY_SERVER_PRIVATE_KEY=the_private_key_contents

That's it, you're ready to deploy....

After the build and deploy succeeded, try to curl in your server curl localhost:5009
