Installation and Configuration Guide

Harbor can be installed in one of two ways:

  1. From source code - This goes through a full build process, and requires an Internet connection.
  2. Pre-built installation package - This can save time (no building necessary!) as well as allows for installation on a host that is not connected to the Internet.

This guide describes both of these approaches.

In addition, the deployment instructions on Kubernetes has been created by the community. Refer to Deploy Harbor on Kubernetes for details.

Prerequisites for the target host

Harbor is deployed as several Docker containers, and, therefore, can be deployed on any Linux distribution that supports Docker. The target host requires Python, Docker, and Docker Compose to be installed.

  • Python should be version 2.7 or higher. Note that you may have to install Python on Linux distributions (Gentoo, Arch) that do not come with a Python interpreter installed by default
  • Docker engine should be version 1.10 or higher. For installation instructions, please refer to: https://docs.docker.com/engine/installation/
  • Docker Compose needs to be version 1.6.0 or higher. For installation instructions, please refer to: https://docs.docker.com/compose/install/

Installation from source code

Note: To install from source, the target host must be connected to the Internet! The steps boil down to the following

  1. Get the source code
  2. Configure harbor.cfg
  3. prepare the configuration files
  4. Start Harbor with Docker Compose

Getting the source code:

$ git clone https://github.com/vmware/harbor

Configuring Harbor

Configuration parameters are located in the file harbor.cfg. The parameters are described below - note that at the very least, you will need to change the hostname attribute.

  • hostname: The target host's hostname, which is used to access the UI and the registry service. It should be the IP address or the fully qualified domain name (FQDN) of your target machine, e.g., 192.168.1.10 or reg.yourdomain.com. Do NOT use localhost or 127.0.0.1 for the hostname - the registry service needs to be accessible by external clients!

  • ui_url_protocol: (http or https. Default is http) The protocol used to access the UI and the token/notification service. By default, this is http. To set up the https protocol, refer to Configuring Harbor with HTTPS Access.

  • Email settings: These parameters are needed for Harbor to be able to send a user a "password reset" email, and are only necessary if that functionality is needed. Also, do note that by default SSL connectivity is not enabled - if your SMTP server requires SSL, but does not support STARTTLS, then you should enable SSL by setting email_ssl = true.

  • harbor_admin_password: The adminstrator's password. Note that the default username/password are admin/Harbor12345 .

  • auth_mode: The type of authentication that is used. By default it is db_auth, i.e. the credentials are stored in a database. For LDAP authentication, set this to ldap_auth.

  • ldap_url: The LDAP endpoint URL (e.g. ldaps://ldap.mydomain.com). Only used when auth_mode is set to ldap_auth .

  • ldap_basedn: The basedn template for verifying the user's credentials against LDAP (e.g. uid=%s,ou=people,dc=mydomain,dc=com). Only used when auth_mode is set to ldap_auth .

  • db_password: The root password for the mySQL database used for db_auth. Change this password for any production use!

  • self_registration: (on or off. Default is on) Enable / Disable the ability for a user to register themselves. When disabled, new users can only be created by the Admin user, only an admin user can create new users in Harbor. NOTE: When auth_mode is set to ldap_auth, self-registration feature is always disabled, and this flag is ignored.

Building and starting Harbor

Once harbord.cfg is configured, build and start Harbor as follows. Note that the docker-compose process can take a while.

    $ cd Deploy
    
    $ ./prepare
    Generated configuration file: ./config/ui/env
    Generated configuration file: ./config/ui/app.conf
    Generated configuration file: ./config/registry/config.yml
    Generated configuration file: ./config/db/env
    The configuration files are ready, please use docker-compose to start the service.

    $ sudo docker-compose up -d

If everything worked properly, you should be able to open a browser to visit the admin portal at http://reg.yourdomain.com . Note that the default administrator username/password are admin/Harbor12345 .

Log in to the admin portal and create a new project, e.g. myproject. You can then use docker commands to login and push images (By default, the registry server listens on port 80):

$ docker login reg.yourdomain.com
$ docker push reg.yourdomain.com/myproject/myrepo

NOTE: The default installation of Harbor uses HTTP - as such, you will need to add the option --insecure-registry to your client's Docker daemon and restart the Docker service.

For information on how to use Harbor, please refer to User Guide of Harbor .

Configuring Harbor with HTTPS access

Harbor does not ship with any certificates, and, by default, uses HTTP to serve requests. While this makes it relatively simple to set up and run - especially for a development or testing environment - it is not recommended for a production environment. To enable HTTPS, please refer to Configuring Harbor with HTTPS Access.

Configuring storage backend

By default, Harbor stores images on your local filesystem. In a production environment, you may consider using other storage backend instead of the local filesystem, like S3, Openstack Swift, Ceph, etc. What you need is to update the section of storage in the file Deploy/templates/registry/config.yml. For example, if you use Openstack Swift as your storage backend, the section may look like this:

storage:
  swift:
    username: admin
    password: ADMIN_PASS
    authurl: http://keystone_addr:35357/v3
    tenant: admin
    domain: default
    region: regionOne
    container: docker_images

Next, run prepare script to generate the configuration files and docker-compose to build and start Harbor.

NOTE: For detailed information on storage backend of a registry, refer to Registry Configuration Reference .

Installation from a pre-built package

Pre-built installation packages of each release are available at release page. Download the package file harbor-<version>.tgz , and then extract the files.

$ tar -xzvf harbor-0.1.1.tgz
$ cd harbor

Next, configure Harbor as described earlier in Configuring Harbor.

Finally, run the prepare script to generate config files, and use docker compose to build and start Harbor.

$ ./prepare
Generated configuration file: ./config/ui/env
Generated configuration file: ./config/ui/app.conf
Generated configuration file: ./config/registry/config.yml
Generated configuration file: ./config/db/env
The configuration files are ready, please use docker-compose to start the service.

$ sudo docker-compose up -d
......

Deploying Harbor on a host which does not have Internet access

docker-compose up pulls the base images from Docker Hub and builds new images for the containers, which, necessarily, requires Internet access. To deploy Harbor on a host that is not connected to the Internet

  1. Prepare Harbor on a machine that has access to the Internet.
  2. Export the images as tgz files
  3. Transfer them to the target host.
  4. Load the tgz file into Docker's local image repo on the host.

These steps are detailed below:

Building and saving images for offline installation

On a machine that is connected to the Internet,

  1. Extract the files from the pre-built installation package.
  2. Then, run docker-compose build to build the images.
  3. Use the script save_image.sh to export these images as tar files. Note that the tar files will be stored in the images/ directory.
  4. Package everything in the directory harbor/ into a tgz file
  5. Transfer this tgz file to the target machine.

The commands, in detail, are as follows:

$ cd harbor
$ sudo docker-compose build
......
$ sudo ./save_image.sh  
saving the image of harbor_ui
finished saving the image of harbor_ui
saving the image of harbor_log
finished saving the image of harbor_log
saving the image of harbor_mysql
finished saving the image of harbor_mysql
saving the image of nginx
finished saving the image of nginx
saving the image of registry
finished saving the image of registry
$ cd ../  
$ tar -cvzf harbor_offline-0.1.1.tgz harbor

The file harbor_offline-0.1.1.tgz contains the images and other files required to start Harbor. You can use tools such as rsync or scp to transfer this file to the target host. On the target host, execute the following commands to start Harbor. Note that before running the prepare script, you must update harbor.cfg to reflect the right configuration of the target machine! (Refer to Section Configuring Harbor).

$ tar -xzvf harbor_offline-0.1.1.tgz  
$ cd harbor  

# load images save by excute ./save_image.sh
$ ./load_image.sh
loading the image of harbor_ui
finish loaded the image of harbor_ui
loading the image of harbor_mysql
finished loading the image of harbor_mysql
loading the image of nginx
finished loading the image of nginx
loading the image of registry
finished loading the image of registry

# Make update to the parameters in ./harbor.cfg  
$ ./prepare
Generated configuration file: ./config/ui/env
Generated configuration file: ./config/ui/app.conf
Generated configuration file: ./config/registry/config.yml
Generated configuration file: ./config/db/env
The configuration files are ready, please use docker-compose to start the service.

# Build the images and then start the services
$ sudo docker-compose up -d

Managing Harbor's lifecycle

You can use docker-compose to manage the lifecycle of the containers. A few useful commands are listed below:

Build and start Harbor:

$ sudo docker-compose up -d 
Creating harbor_log_1
Creating harbor_mysql_1
Creating harbor_registry_1
Creating harbor_ui_1
Creating harbor_proxy_1

Stop Harbor:

$ sudo docker-compose stop
Stopping harbor_proxy_1 ... done
Stopping harbor_ui_1 ... done
Stopping harbor_registry_1 ... done
Stopping harbor_mysql_1 ... done
Stopping harbor_log_1 ... done

Restart Harbor after stopping:

$ sudo docker-compose start
Starting harbor_log_1
Starting harbor_mysql_1
Starting harbor_registry_1
Starting harbor_ui_1
Starting harbor_proxy_1

Remove Harbor's containers while keeping the image data and Harbor's database files on the file system:

$ sudo docker-compose rm
Going to remove harbor_proxy_1, harbor_ui_1, harbor_registry_1, harbor_mysql_1, harbor_log_1
Are you sure? [yN] y
Removing harbor_proxy_1 ... done
Removing harbor_ui_1 ... done
Removing harbor_registry_1 ... done
Removing harbor_mysql_1 ... done

Remove Harbor's database and image data (for a clean re-installation):

$ rm -r /data/database
$ rm -r /data/registry

Please check the Docker Compose command-line reference for more on docker-compose.

Persistent data and log files

By default, registry data is persisted in the target host's /data/ directory. This data remains unchanged even when Harbor's containers are removed and/or recreated. In addition, Harbor uses rsyslog to collect the logs of each container. By default, these log files are stored in the directory /var/log/harbor/ on the target host.

##Troubleshooting 1.When setting up Harbor behind an nginx proxy or elastic load balancing, look for the line below, in Deploy/config/nginx/nginx.conf and remove it from the sections if the proxy already has similar settings: location /, location /v2/ and location /service/.

proxy_set_header X-Forwarded-Proto $scheme;
