- **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.yml``` 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 using Helm](https://github.com/goharbor/harbor-helm) 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 Docker, and Docker Compose to be installed.
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.
- **System level parameters**: These parameters are required to be set in the configuration file. They will take effect if a user updates them in ```harbor.yml``` and run the ```install.sh``` script to reinstall Harbor.
- **User level parameters**: These parameters can update after the first time harbor started on Web Portal. 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 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` or `0.0.0.0` for the hostname - the registry service needs to be accessible by external clients!_
- **data_volume**: The location to store harbor's data.
- **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** ._
- **database**: the configs related to local database
- **password**: The root password for the PostgreSQL database. Change this password for any production use.
- **max_idle_conns**: The maximum number of connections in the idle connection pool. If <=0 no idle connections are retained. The default value is 50 and if it is not configured the value is 2.
- **max_open_conns**: The maximum number of open connections to the database. If <= 0 there is no limit on the number of open connections. The default value is 100 for the max connections to the Harbor database. If it is not configured the value is 0.
- **max_job_workers**: 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.
- **local**: The default is to retain logs locally.
- **rotate_count**: Log files are rotated **rotate_count** times before being removed. If count is 0, old versions are removed rather than rotated.
- **rotate_size**: Log files are rotated only if they grow bigger than **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.
- **location**: the directory to store logs
- **external_endpoint**: Enable this option to forward logs to a syslog server.
- **protocol**: Transport protocol for the syslog server. Default is TCP.
- **host**: The URL of the syslog server.
- **port**: The port on which the syslog server listens.
- **max_idle_conns**: The maximum number of connections in the idle connection pool. If <=0 no idle connections are retained. The default value is 2.
- **max_open_conns**: The maximum number of open connections to the database. If <= 0 there is no limit on the number of open connections. The default value is 0.
- **storage_service**: By default, Harbor stores images and chart on your local filesystem. In a production environment, you may consider use other storage backend instead of the local filesystem, like S3, OpenStack Swift, Ceph, etc. These parameters are configurations for registry.
- **ca_bundle**: The path to the custom root ca certificate, which will be injected into the trust store of registry's and chart repository's containers. This is usually needed when the user hosts a internal storage with self signed certificate.
- **provider_name**: Storage configs for registry, default is filesystem. for more info about this configuration please refer https://docs.docker.com/registry/configuration/
- **redirect**:
- **disable**: set disable to true when you want to disable registry redirect
_NOTE: For detailed information on storage backend of a registry, refer to [Registry Configuration Reference](https://docs.docker.com/registry/configuration/) ._
Once **harbor.yml** 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.yml`). 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.
More information about Notary and Docker Content Trust, please refer to [Docker's documentation](https://docs.docker.com/engine/security/trust/content_trust/).
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*).
To change Harbor's configuration, first stop existing Harbor instance and update `harbor.yml`. Then run `prepare` script to populate the configuration. Finally re-create and start Harbor's instance:
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, you can edit the `data_volume` in `harbor.yml` file to change this directory.
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, also you can change the log directory in `harbor.yml`.
By default, Harbor listens on port 80(HTTP) and 443(HTTPS, if configured) for both admin portal and docker commands, these default ports can configured in `harbor.yml`
Currently, only PostgreSQL database is supported by Harbor.
To user an external database, just uncomment the `external_database` section in `harbor.yml` and fill the necessary information. Four databases are needed to be create first by users for Harbor core, Clair, Notary server and Notary signer. And the tables will be generated automatically when Harbor starting up.
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.
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/config/nginx/nginx.conf` and remove it from the sections if the proxy already has similar settings: `location /`, `location /v2/` and `location /service/`.
