- **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.
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](migration_guide.md)**.
In addition, the deployment instructions on Kubernetes has been created by the community. Refer to [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|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|
The binary of the installer can be downloaded from the [release](https://github.com/goharbor/harbor/releases) page. Choose either online or offline installer. Use *tar* command to extract the package.
* **required parameters**: These parameters are required to be set in the configuration file. They will take effect if a user updates them in ```harbor.cfg``` and run the ```install.sh``` script to reinstall Harbor.
* **optional parameters**: These parameters are optional for updating, i.e. user can leave them as default and update them on Web Portal after Harbor is started. If they are set in ```harbor.cfg```, they only take effect in the first launch of 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),
* **hostname**: The target host's hostname, which is used to access the Portal 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 Portal 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](configure_https.md)**.
* **db_password**: The root password for the PostgreSQL database used for **db_auth**. _Change this password for any production use!_
* **max_job_workers**: (default value is **10**) 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](customize_token_service.md) for more info.
* **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](https://tools.ietf.org/rfc/rfc2595.txt)
* **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 Portal. _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.cfg``` before launching the new version of Harbor. Otherwise, users
* **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
* **registry_storage_provider_name**: Storage provider name of registry, it can be filesystem, s3, gcs, azure, etc. Default is filesystem.
* **registry_storage_provider_config**: Comma separated "key: value" pairs for storage provider config, e.g. "key1: value, key2: value2". Default is empty string.
* **registry_custom_ca_bundle**: The path to the custom root ca certificate, which will be injected into the truststore of registry's and chart repository's containers. This is usually needed when the user hosts a internal storage with self signed certificate.
For example, if you use Openstack Swift as your storage backend, the parameters may look like this:
_NOTE: For detailed information on storage backend of a registry, refer to [Registry Configuration Reference](https://docs.docker.com/registry/configuration/) ._
#### 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.
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.
**Note**: For installation with Notary the parameter **ui_url_protocol** must be set to "https". For configuring HTTPS please refer to the following sections.
For information on how to use Harbor, please refer to **[User Guide of Harbor](user_guide.md)** .
#### 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](configure_https.md)**.
### 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*).
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:
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:
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:
#### _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:
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:
```sh
$ 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:
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:
```sh
$ 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:
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
1.Modify docker-compose.yml
Replace the first "80" to a customized port, e.g. 8888:80.
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.
harbor-log /bin/sh -c /usr/local/bin/ ... Up 127.0.0.1:1514->10514/tcp
harbor-portal nginx -g daemon off; Up 80/tcp
nginx nginx -g daemon off; Up 0.0.0.0:443->443/tcp, 0.0.0.0:4443->4443/tcp, 0.0.0.0:80->80/tcp
redis docker-entrypoint.sh redis ... Up 6379/tcp
registry /entrypoint.sh /etc/regist ... Up 5000/tcp
registryctl /harbor/start.sh Up
```
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 ```core.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/`.
