Installation and Configuration Guide
Harbor can be installed by one of three approaches:
Online installer: The installer downloads Harbor's images from Docker hub. For this reason, the installer is very small in size.
Offline installer: Use this installer when the host does not have an Internet connection. The installer contains pre-built images so its size is larger.
All installers can be downloaded from the official release page.
This guide describes the steps to install and configure Harbor by using the online or offline installer. The installation processes are almost the same.
If you run a previous version of Harbor, you may need to update
harbor.cfg and migrate the data to fit the new database schema. For more details, please refer to Harbor Migration Guide.
In addition, the deployment instructions on Kubernetes has been created by the community. Refer to 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.
|CPU||minimal 2 CPU||4 CPU is preferred|
|Mem||minimal 4GB||8GB is preferred|
|Disk||minimal 40GB||160GB is preferred|
|Python||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||version 1.10 or higher||For installation instructions, please refer to: https://docs.docker.com/engine/installation/|
|Docker Compose||version 1.6.0 or higher||For installation instructions, please refer to: https://docs.docker.com/compose/install/|
|Openssl||latest is preferred||Generate certificate and keys for Harbor|
|443||HTTPS||Harbor UI and API will accept requests on this port for https protocol|
|4443||HTTPS||Connections to the Docker Content Trust service for Harbor, only needed when Notary is enabled|
|80||HTTP||Harbor UI and API will accept requests on this port for http protocol|
The installation steps boil down to the following
- Download the installer;
- Configure harbor.cfg;
- Run install.sh to install and start Harbor;
Downloading the installer:
The binary of the installer can be downloaded from the release page. Choose either online or offline installer. Use tar command to extract the package.
$ tar xvf harbor-online-installer-<version>.tgz
$ tar xvf harbor-offline-installer-<version>.tgz
Configuration parameters are located in the file harbor.cfg.
There are two categories of parameters in harbor.cfg, required parameters and optional parameters.
required parameters: These parameters are required to be set in the configuration file. They will take effect if a user updates them in
harbor.cfgand run the
install.shscript to reinstall Harbor.
optional parameters: These parameters are optional for updating, i.e. user can leave them as default and update them on Web UI after Harbor is started. If they are set in
harbor.cfg, they only take effect in the first launch of Harbor. Subsequent update to these parameters in
harbor.cfgwill be ignored.
Note: If you choose to set these parameters via the UI, be sure to do so right after Harbor is started. In particular, you must set the desired auth_mode before registering or creating any new users in Harbor. When there are users in the system (besides the default admin user), auth_mode cannot be changed.
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.,
reg.yourdomain.com. Do NOT use
127.0.0.1for 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. If Notary is enabled, this parameter has to be https. By default, this is http. To set up the https protocol, refer to Configuring Harbor with HTTPS Access.
- db_password: The root password for the MySQL database used for db_auth. Change this password for any production use!
- max_job_workers: (default value is 3) The maximum number of replication workers in job service. For each image replication job, a worker synchronizes all tags of a repository to the remote destination. Increasing this number allows more concurrent replication jobs in the system. However, since each worker consumes a certain amount of network/CPU/IO resources, please carefully pick the value of this attribute based on the hardware resource of the host.
- customize_crt: (on or off. Default is on) When this attribute is on, the prepare script creates private key and root certificate for the generation/verification of the registry's token. Set this attribute to off when the key and root certificate are supplied by external sources. Refer to Customize Key and Certificate of Harbor Token Service for more info.
- ssl_cert: The path of SSL certificate, it's applied only when the protocol is set to https
- ssl_cert_key: The path of SSL key, it's applied only when the protocol is set to https
- secretkey_path: The path of key for encrypt or decrypt the password of a remote registry in a replication policy.
- log_rotate_count: Log files are rotated log_rotate_count times before being removed. If count is 0, old versions are removed rather than rotated.
- log_rotate_size: Log files are rotated only if they grow bigger than log_rotate_size bytes. If size is followed by k, the size is assumed to be in kilobytes. If the M is used, the size is in megabytes, and if G is used, the size is in gigabytes. So size 100, size 100k, size 100M and size 100G are all valid.
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. Setting email_insecure = true if the email server uses a self-signed or untrusted certificate. For a detailed description about "email_identity" please refer to rfc2595
harbor_admin_password: The administrator's initial password. This password only takes effect for the first time Harbor launches. After that, this setting is ignored and the administrator's password should be set in the UI. 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.
IMPORTANT: When upgrading from an existing Harbor instance, you must make sure auth_mode is the same in
harbor.cfgbefore launching the new version of Harbor. Otherwise, users may not be able to log in after the upgrade.
ldap_url: The LDAP endpoint URL (e.g.
ldaps://ldap.mydomain.com). Only used when auth_mode is set to ldap_auth .
ldap_searchdn: The DN of a user who has the permission to search an LDAP/AD server (e.g.
ldap_search_pwd: The password of the user specified by ldap_searchdn.
ldap_basedn: The base DN to look up a user, e.g.
ou=people,dc=mydomain,dc=com. Only used when auth_mode is set to ldap_auth .
ldap_filter:The search filter for looking up a user, e.g.
ldap_uid: The attribute used to match a user during a LDAP search, it could be uid, cn, email or other attributes.
ldap_scope: The scope to search for a user, 0-LDAP_SCOPE_BASE, 1-LDAP_SCOPE_ONELEVEL, 2-LDAP_SCOPE_SUBTREE. Default is 2.
self_registration: (on or off. Default is on) Enable / Disable the ability for a user to register himself/herself. 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.
token_expiration: The expiration time (in minutes) of a token created by token service, default is 30 minutes.
project_creation_restriction: The flag to control what users have permission to create projects. By default everyone can create a project, set to "adminonly" such that only admin can create project.
Configuring storage backend (optional)
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 to update is the section of
storage in the file
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/auth tenant: admin domain: default region: regionOne container: docker_images
NOTE: For detailed information on storage backend of a registry, refer to Registry Configuration Reference .
Finishing installation and starting Harbor
Once harbor.cfg and storage backend (optional) are configured, install and start Harbor using the
install.sh script. Note that it may take some time for the online installer to download Harbor images from Docker hub.
Default installation (without Notary/Clair)
Harbor has integrated with Notary and Clair (for vulnerability scanning). However, the default installation does not include Notary or Clair service.
$ sudo ./install.sh
If everything worked properly, you should be able to open a browser to visit the admin portal at http://reg.yourdomain.com (change reg.yourdomain.com to the hostname configured in your
harbor.cfg). 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:mytag
IMPORTANT: 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.
Installation with Notary
To install Harbor with Notary service, add a parameter when you run
$ sudo ./install.sh --with-notary
Note: For installation with Notary the parameter ui_url_protocol must be set to "https". For configuring HTTPS please refer to the following sections.
More information about Notary and Docker Content Trust, please refer to Docker's documentation: https://docs.docker.com/engine/security/trust/content_trust/
Installation with Clair
To install Harbor with Clair service, add a parameter when you run
$ sudo ./install.sh --with-clair
For more information about Clair, please refer to Clair's documentation: https://coreos.com/clair/docs/2.0.1/
Installation with chart repository service
To install Harbor with chart repository service, add a parameter when you run
$ sudo ./install.sh --with-chartmuseum
Note: If you want to install Notary, Clair and chart repository service, you must specify all the parameters in the same command:
$ sudo ./install.sh --with-notary --with-clair --with-chartmuseum
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.
Managing Harbor's lifecycle
You can use docker-compose to manage the lifecycle of Harbor. Some useful commands are listed as follows (must run in the same directory as docker-compose.yml).
$ sudo docker-compose stop Stopping nginx ... done Stopping harbor-jobservice ... done Stopping harbor-core ... done Stopping harbor-db ... done Stopping registry ... done Stopping harbor-log ... done
Restarting Harbor after stopping:
$ sudo docker-compose start Starting log ... done Starting ui ... done Starting mysql ... done Starting jobservice ... done Starting registry ... done Starting proxy ... done
To change Harbor's configuration, first stop existing Harbor instance and update
harbor.cfg. Then run
prepare script to populate the configuration. Finally re-create and start Harbor's instance:
$ sudo docker-compose down -v $ vim harbor.cfg $ sudo prepare $ sudo docker-compose up -d
Removing Harbor's containers while keeping the image data and Harbor's database files on the file system:
$ sudo docker-compose down -v
Removing Harbor's database and image data (for a clean re-installation):
$ rm -r /data/database $ rm -r /data/registry
Managing lifecycle of Harbor when it's installed with Notary
When Harbor is installed with Notary, an extra template file
docker-compose.notary.yml is needed for docker-compose commands. The docker-compose commands to manage the lifecycle of Harbor are:
$ sudo docker-compose -f ./docker-compose.yml -f ./docker-compose.notary.yml [ up|down|ps|stop|start ]
For example, if you want to change configuration in
harbor.cfg and re-deploy Harbor when it's installed with Notary, the following commands should be used:
$ sudo docker-compose -f ./docker-compose.yml -f ./docker-compose.notary.yml down -v $ vim harbor.cfg $ sudo prepare --with-notary $ sudo docker-compose -f ./docker-compose.yml -f ./docker-compose.notary.yml up -d
Managing lifecycle of Harbor when it's installed with Clair
When Harbor is installed with Clair, an extra template file
docker-compose.clair.yml is needed for docker-compose commands. The docker-compose commands to manage the lifecycle of Harbor are:
$ sudo docker-compose -f ./docker-compose.yml -f ./docker-compose.clair.yml [ up|down|ps|stop|start ]
For example, if you want to change configuration in
harbor.cfg and re-deploy Harbor when it's installed with Clair, the following commands should be used:
$ sudo docker-compose -f ./docker-compose.yml -f ./docker-compose.clair.yml down -v $ vim harbor.cfg $ sudo prepare --with-clair $ sudo docker-compose -f ./docker-compose.yml -f ./docker-compose.clair.yml up -d
Managing lifecycle of Harbor when it's installed with chart repository service
When Harbor is installed with chart repository service, an extra template file
docker-compose.chartmuseum.yml is needed for docker-compose commands. The docker-compose commands to manage the lifecycle of Harbor are:
$ sudo docker-compose -f ./docker-compose.yml -f ./docker-compose.chartmuseum.yml [ up|down|ps|stop|start ]
For example, if you want to change configuration in
harbor.cfg and re-deploy Harbor when it's installed with chart repository service, the following commands should be used:
$ sudo docker-compose -f ./docker-compose.yml -f ./docker-compose.chartmuseum.yml down -v $ vim harbor.cfg $ sudo prepare --with-chartmuseum $ sudo docker-compose -f ./docker-compose.yml -f ./docker-compose.chartmuseum.yml up -d
Managing lifecycle of Harbor when it's installed with Notary, Clair and chart repository service
If you want to install Notary, Clair and chart repository service together, you should include all the components in the docker-compose and prepare commands:
$ sudo docker-compose -f ./docker-compose.yml -f ./docker-compose.notary.yml -f ./docker-compose.clair.yml -f ./docker-compose.chartmuseum.yml down -v $ vim harbor.cfg $ sudo prepare --with-notary --with-clair --with-chartmuseum $ sudo docker-compose -f ./docker-compose.yml -f ./docker-compose.notary.yml -f ./docker-compose.clair.yml -f ./docker-compose.chartmuseum.yml up -d
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 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 for troubleshooting.
Configuring Harbor listening on a customized port
By default, Harbor listens on port 80(HTTP) and 443(HTTPS, if configured) for both admin portal and docker commands, you can configure it with a customized one.
For HTTP protocol
Replace the first "80" to a customized port, e.g. 8888:80.
proxy: image: library/nginx:1.11.5 restart: always volumes: - ./config/nginx:/etc/nginx ports: - 8888:80 - 443:443 depends_on: - mysql - registry - ui - log logging: driver: "syslog" options: syslog-address: "tcp://127.0.0.1:1514" tag: "proxy"
2.Modify harbor.cfg, add the port to the parameter "hostname"
hostname = 192.168.0.2:8888
3.Re-deploy Harbor referring to previous section "Managing Harbor's lifecycle".
For HTTPS protocol
1.Enable HTTPS in Harbor by following this guide.
Replace the first "443" to a customized port, e.g. 8888:443.
proxy: image: library/nginx:1.11.5 restart: always volumes: - ./config/nginx:/etc/nginx ports: - 80:80 - 8888:443 depends_on: - mysql - registry - ui - log logging: driver: "syslog" options: syslog-address: "tcp://127.0.0.1:1514" tag: "proxy"
3.Modify harbor.cfg, add the port to the parameter "hostname"
hostname = 192.168.0.2:8888
4.Re-deploy Harbor referring to previous section "Managing Harbor's lifecycle".
By default, Harbor limits the CPU usage of Clair container to 150000 and avoids its using up all the CPU resources. This is defined in the docker-compose.clair.yml file. You can modify it based on your hardware configuration.
- When Harbor does not work properly, run the below commands to find out if all containers of Harbor are in UP status:
$ sudo docker-compose ps Name Command State Ports ----------------------------------------------------------------------------------------------------- harbor-db docker-entrypoint.sh mysqld Up 3306/tcp harbor-jobservice /harbor/harbor_jobservice Up harbor-log /bin/sh -c crond && rsyslo ... Up 127.0.0.1:1514->514/tcp harbor-core /harbor/harbor_core Up nginx nginx -g daemon off; Up 0.0.0.0:443->443/tcp, 0.0.0.0:80->80/tcp registry /entrypoint.sh serve /etc/ ... Up 5000/tcp
If a container is not in UP state, check the log file of that container in directory
/var/log/harbor. For example, if the container
harbor-core is not running, you should look at the log file
2.When setting up Harbor behind an nginx proxy or elastic load balancing, look for the line below, in
common/templates/nginx/nginx.http.conf and remove it from the sections if the proxy already has similar settings:
location /v2/ and
proxy_set_header X-Forwarded-Proto $scheme;
and re-deploy Harbor refer to the previous section "Managing Harbor's lifecycle".
