$ sudo chown -R nexus:nexus /opt/sonatype-work nexus ALL=(ALL) NOPASSWD: ALLĬhange file and owner permission for nexus files $ sudo chown -R nexus:nexus /opt/nexus Set no password for nexus user and enter below command to edit sudo file $sudo visudoĪdd the below line and Save. so create a new user called nexus and grant sudo access to manage nexus services. $ sudo mv /opt/nexus-3.16.1-02 /opt/nexusĪs a good security practice, it is not advised to run nexus service as root. If you want to pull the image, you can do so as wellĪfter pushing the image if you go to the browse section and click on your repository, you will see your docker image.$ sudo apt install openjdk-8-jre-headless -y Tag the docker image using your nexus IP as shown below:ĭocker tag alpine 192.168.99.109:8083/myalpine:latestĭocker push 192.168.99.109:8083/myalpine:latest You can choose any private IP ad you like. Next, install docker on it, and then create a daemon.json file in the /etc/docker location. Make sure the Nexus VM is reachable from this client machine. Test the connection from the host machine, assuming that password is Password123 the username is dockerĭocker login -u docker 192.168.99.109:8083 -pPassword123Ĭreate an VM that will simulate the client machine. Next, click on ‘Realms’ under security and active the “Docker Bearder Token Realm” as shown below. After logining in, you need to change the admin password and then create a role for the docker:Ĭreate a user and add the username in the role. Login to the nexus using The default admin user name is admin. The admin password is located in the /nexus-data/admin.password file in the container.

Type a name for the repository and set the HTTP port 8083 that we have opened earlier on the container while running it.

Note: here, we will use port 8083 for docker repository connector. The connector will be used to push/pull docker image to the nexus reposition from a host machine.ĭocker run -d -p 8081:8081 -p 8083:8083 –name nexus -v nexus-data:/nexus-data sonatype/nexus3 You also need to expose another random port that we will use as a connector port. Remember that nexus container will be exposed on port 8081. Ĭreate a docker volume and run the Nexus container You can either install the docker in your host machine or you can install a Ubuntu virtual box and then install docker on it.Īt first create Ubuntu virtual machine and then install docker. Scenario: To create a private docker repository in your local machine for development purpose, you can deploy a Nexus3 docker image with a persistent volume in a minute.
