- **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.
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](migration_guide.md)**.
In addition, the deployment instructions on Kubernetes has been created by the community. Refer to set up [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/
The binary of the installer can be downloaded from the [release](https://github.com/vmware/harbor/releases) page. Choose either online or offline installer. Use *tar* command to extract the package.
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 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**.
* **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.
* **secret_key**: The key to encrypt or decrypt the password of a remote registry in a replication policy, its length has to be 16 characters. Change this key before any production use. *NOTE: After changing this key, previously encrypted password of a policy can not be decrypted.*
* **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](customize_token_service.md) for more info.
_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, 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.
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):
**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.
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)**.
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*).
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.
## 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.
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_1``` is not running, you should look at the log file ```docker_ui.log```.
2.When setting up Harbor behind an nginx proxy or elastic load balancing, look for the line below, in `make/config/nginx/nginx.conf` and remove it from the sections if the proxy already has similar settings: `location /`, `location /v2/` and `location /service/`.
