Harbor is an open-source enterprise-class registry server that stores and distributes Docker images. Harbor extends the open source Docker Distribution by adding the functionalities usually required by an enterprise, such as security, identity and management. As an enterprise private registry, Harbor offers better performance and security. Having a registry closer to the build and run environment improves the image transfer efficiency. Harbor supports the setup of multiple registries and has images replicated between them. In addition, Harbor offers advanced security features, such as user management, access control and activity auditing.
- An IT Web Services CentOS 7 server instance with at least 1GB RAM.
- A non-root user with sudo privileges setup on your server.
Before starting, you will need to install the
EPEL repo and other required packages to your system.
sudo yum install epel-release wget -y
Once the installation is completed, update your system to the latest version.
sudo yum update -y
Next, restart your system to apply all the updates.
sudo shutdown -r now
In this tutorial, we will use
harbor.example.com as the domain name pointed to the server. Replace all occurrences of
harbor.example.com with your actual domain name.
Install Docker and Docker-Compose
Harbor is deployed as several Docker containers. Therefore, it can be deployed on any Linux distribution that supports Docker. The target host requires that Docker and Docker Compose be installed.
Install Docker CE using the repository.
sudo yum install -y yum-utils sudo yum-config-manager --add-repo https://download.docker.com/linux/centos/docker-ce.repo sudo yum install -y docker-ce
Install Docker-Compose using
sudo yum install -y python-pip pip install docker-compose
sudo systemctl start docker
Verify that docker is installed correctly by running the
sudo docker run hello-world
The binary of the installer can be downloaded from the release page. Choose either the online or offline installer.
tar command to extract the package.
tar -xvf harbor-online-installer-1.2.0.tgz
Generate your own SSL certificate
The default installation of Harbor uses
HTTP – as such, you will need to add the option
--insecure-registry to your client’s Docker daemon, then restart the Docker service. Installing Harbor with
HTTPS is highly recommended. It will save us a lot of time in the future. Generate your own SSL certificate (replace
harbor.example.com with your host’s FQDN).
mkdir cert && cd cert openssl req -sha256 -x509 -days 365 -nodes -newkey rsa:4096 -keyout harbor.example.com.key -out harbor.example.com.crt
Edit the Harbor config file.
hostname to your host’s FQDN and enable
hostname = harbor.example.com ui_url_protocol = https ssl_cert = /root/cert/harbor.example.com.crt ssl_cert_key = /root/cert/harbor.example.com.key
install.sh to finish the installation.
Run Harbor in the background.
docker-compose up -d
Access Harbor Web Interface
Before starting, you will need to allow port
80 through the firewall.
sudo firewall-cmd --permanent --zone=public --add-port=80/tcp sudo firewall-cmd --reload
You can access the Harbor server on
http://harobr.example.com if you have DNS configured. Login using the default
The installation and basic configuration of Harbor is now complete.
