Setup Artifactory on Ubuntu 16.0.4 using Docker - Install JFrog Artifactory on Ubuntu

Artifactory is one of the popular Binary repository manager. It is Java based tool, used for storing artifacts. Artifactory can be integrated with many Continuous integration and Continuous delivery tools. Artifactory is mainly used by Ant, Maven and Gradle build tools.

Let us see how to configure Artifactory on Ubuntu 16.0.4 using Docker. We will configure Artifactory by doing the three steps:

1. Install Docker on Ubuntu 16.0.4
2. Download Artifactory image
3. Spin up a container using the Artifactory image 

1. Install Docker on Ubuntu

Install packages to allow apt to use a repository over HTTPS:

sudo apt -y install apt-transport-https ca-certificates curl software-properties-common

Add Docker’s official GPG key:
curl -fsSL https://download.docker.com/linux/ubuntu/gpg | sudo apt-key add -

Add stable repository:
sudo add-apt-repository "deb [arch=amd64] https://download.docker.com/linux/ubuntu $(lsb_release -cs) stable"

Install Docker CE:
sudo apt update && sudo apt -y install docker-ce

If you would like to use Docker as a non-root user, you should now consider adding your user to the “docker” group with something like:
sudo usermod -aG docker $USER

Run the command below to see a version of docker installed.
docker version
 Client:
 Version:           18.09.6
 API version:       1.39
 Go version:        go1.10.8
 Git commit:        481bc77
 Built:             Sat May  4 02:35:27 2019
 OS/Arch:           linux/amd64
 Experimental:      false

Step 2: Download Artifactory Docker image

There are different editions of JFrog Artifactory available, let us use open source version.

Pull the latest Docker image of JFrog Artifactory.
sudo docker pull docker.bintray.io/jfrog/artifactory-oss:latest

Display docker images
sudo docker images

Step 3: Create Data Directory

Create data directory on host system to ensure data used on container is persistent.
sudo mkdir -p /jfrog/artifactory
sudo chown -R 1030 /jfrog/

Step 4: Start JFrog Artifactory container

To start an Artifactory container, use the command:
sudo docker run --name artifactory -d -p 8081:8081 \
 -v /jfrog/artifactory:/var/opt/jfrog/artifactory \
   docker.bintray.io/jfrog/artifactory-oss:latest
 

Step 5: Run Artifactory as a service

sudo vim /etc/systemd/system/artifactory.service
 
# Copy the below code highlighted in green 
[Unit]
Description=Setup Systemd script for Artifactory Container
After=network.target

[Service]
Restart=always
ExecStartPre=-/usr/bin/docker kill artifactory
ExecStartPre=-/usr/bin/docker rm artifactory
ExecStart=/usr/bin/docker run --name artifactory -p 8081:8081 \
  -v /jfrog/artifactory:/var/opt/jfrog/artifactory \
  docker.bintray.io/jfrog/artifactory-oss:latest
ExecStop=-/usr/bin/docker kill artifactory
ExecStop=-/usr/bin/docker rm artifactory

[Install]
WantedBy=multi-user.target 

Reload Systemd
sudo systemctl daemon-reload

Then start Artifactory container with systemd.
sudo systemctl start artifactory
 
Enable it to start at system boot.
sudo systemctl enable artifactory

Check whether Artifactory is running?
sudo systemctl status artifactory

Step 6: Access Artifactory Web Interface

http://server_url:8081/artifactory

You should see Artifactory welcome page.
