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.
In addition, the deployment instructions on Kubernetes has been created by the community. Refer to [Deploy Harbor on Kubernetes](kubernetes_deployment.md) 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.
* 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/
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](configure_https.md).
* **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 credential against an LDAP (e.g. `uid=%s,ou=people,dc=mydomain,dc=com` ) or an AD (e.g. `CN=%s,OU=Dept1,DC=mydomain,DC=com`) server. _Only used when **auth_mode** is set to *ldap_auth* ._
* **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.
* **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** will bypass 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 regitry'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](customize_token_service.md) for more info.
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
```
_NOTE: For detailed information on storage backend of a registry, refer to [Registry Configuration Reference](https://docs.docker.com/registry/configuration/) ._
Once **harbord.cfg** and storage backend (optional) are configured, build and start Harbor as follows. Note that the docker-compose process can take a while.
_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):
**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.
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](configure_https.md).
*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:
The file `harbor_offline-0.3.0.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](#configuring-harbor)).
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.
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/`.
