Jenkins is one of the oldest and most popular CI/CD tools. It dominates the market and is a requirement for more than 50% of job positions. However, Jenkins is a complicated solution, installing it requires a lot of heavy lifting and can become a pain. In this article, I will uncover the fastest way to deploy Jenkins using only one command.

Step 1. Install Docker

We will need to meet a prerequisite which is having Docker on our system. If you already have docker installed, move straight to Step 2.

Older versions of Docker were called docker, docker.io, or docker-engine. If these are installed, uninstall them:

sudo apt-get remove docker docker-engine docker.io containerd runc

Update the apt package index and install packages to allow apt to use a repository over HTTPS:

sudo apt-get update sudo apt-get install ca-certificates curl gnupg lsb-release

Add Docker’s official GPG key:

curl -fsSL https://download.docker.com/linux/ubuntu/gpg | sudo gpg --dearmor -o /usr/share/keyrings/docker-archive-keyring.gpg

Use the following command to set up the stable repository:

echo \ "deb [arch=$(dpkg --print-architecture) signed-by=/usr/share/keyrings/docker-archive-keyring.gpg] https://download.docker.com/linux/ubuntu \ $(lsb_release -cs) stable" | sudo tee /etc/apt/sources.list.d/docker.list > /dev/null

Update the apt package index, and install the latest version of Docker Engine and containerd, or go to the next step to install a specific version:

sudo apt-get updatesudo apt-get install docker-ce docker-ce-cli containerd.io

More detailed instructions for all supported platforms can be found on a website: https://docs.docker.com/engine/install/ubuntu/

Step 2. The command

I’ll just leave it here:

docker run -d -p 8080:8080 jenkins/jenkins

in this command:
-d starts the container in a daemon mode
-p 8080:8080 exposes the required port to outside

If you want to have persistent storage, you can also bind your local volume inside the container:

docker run -d -p 8080:8080 jenkins/jenkins -v /your/home:/var/jenkins_home

Step 3. Some extra clicks in the UI

Open http://127.0.0.1:8080 in your browser.

Jenkins will ask for an initial password, you can obtain it from docker logs using the following command:

docker logs $(docker ps | grep jenkins | awk '{print $1 }')

Click through the setup wizard, wait until basic plugins are installed, and enjoy your fresh Jenkins installation!
