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.
Virtual Appliance: If you are installing Harbor as the registry component of vSphere Integrated Containers (VIC), or using Harbor as a standalone registry on vSphere platform, download the OVA version of Harbor.
All installers can be downloaded from the official release page.
To install Harbor's virtual appliance, refer to the Harbor Installation Guide for Virtual Appliance.
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 migrate the data to fit the new database schema. For more details, please refer to Data Migration Guide.
In addition, the deployment instructions on Kubernetes has been created by the community. Refer to set up Harbor on Kubernetes for details.
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.
The installation steps boil down to the following
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.
Online installer:
$ tar xvf harbor-online-installer-<version>.tgz
Offline installer:
$ tar xvf harbor-offline-installer-<version>.tgz
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.
admin \<sample_admin@mydomain.com\>
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.
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. uid=admin,ou=people,dc=mydomain,dc=com).
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. (objectClass=person).
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, 1-LDAP_SCOPE_BASE, 2-LDAP_SCOPE_ONELEVEL, 3-LDAP_SCOPE_SUBTREE. Default is 3.
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.
use_compressed_js: (on or off. Default is on) For production use, turn this flag to on. In development mode, set it to off so that js files can be modified separately.
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.
token_expiration: The expiration time (in minutes) of a token created by token service, default is 30 minutes.
verify_remote_cert: (on or off. Default is on) This flag determines whether or not to verify SSL/TLS certificate when Harbor communicates with a remote registry instance. Setting this attribute to off bypasses the SSL/TLS verification, which is often used when the remote instance has a self-signed or untrusted certificate.
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. The following attributes:crt_country, crt_state, crt_location, crt_organization, crt_organizationalunit, crt_commonname, crt_email are used as parameters for generating the keys. 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.
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 common/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/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 .
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.
$ 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.
For information on how to use Harbor, please refer to User Guide of Harbor .
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.
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).
Stopping Harbor:
$ sudo docker-compose stop
Stopping nginx ... done
Stopping harbor-jobservice ... done
Stopping harbor-ui ... 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, update harbor.cfg, and then run install.sh again:
$ sudo docker-compose down
$ vim harbor.cfg
$ sudo install.sh
Removing Harbor's containers while keeping the image data and Harbor's database files on the file system:
$ sudo docker-compose down
Removing 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.
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 for troubleshooting.
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.
1.Modify docker-compose.yml
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 templates/registry/config.yml
Add the customized port, e.g. ":8888", after "$ui_url".
auth:
token:
issuer: registry-token-issuer
realm: $ui_url:8888/service/token
rootcertbundle: /etc/registry/root.crt
service: token-service
3.Run install.sh to update and start Harbor.
$ sudo docker-compose down
$ sudo install.sh
1.Enable HTTPS in Harbor by following this guide.
2.Modify docker-compose.yml
Replace the first "443" to a customized port, e.g. 4443:443.
proxy:
image: library/nginx:1.11.5
restart: always
volumes:
- ./config/nginx:/etc/nginx
ports:
- 80:80
- 4443:443
depends_on:
- mysql
- registry
- ui
- log
logging:
driver: "syslog"
options:
syslog-address: "tcp://127.0.0.1:1514"
tag: "proxy"
3.Modify templates/registry/config.yml
Add the customized port, e.g. ":4443", after "$ui_url".
auth:
token:
issuer: registry-token-issuer
realm: $ui_url:4443/service/token
rootcertbundle: /etc/registry/root.crt
service: token-service
4.Run install.sh to update and start Harbor.
$ sudo docker-compose down
$ sudo install.sh
$ 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 0.0.0.0:1514->514/tcp
harbor-ui /harbor/harbor_ui 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-ui is not running, you should look at the log file ui.log.
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 /, location /v2/ and location /service/.
proxy_set_header X-Forwarded-Proto $scheme;
And run the following commands to restart Harbor:
$ sudo docker-compose down
$ sudo ./prepare
$ sudo docker-compose up -d
