# Build Harbor from Source Code

This guide provides instructions for developers to build and run Harbor from source code.

## Step 1: Prepare for a build environment for Harbor

Harbor is deployed as several Docker containers and most of the code is written in Go language. The build environment requires Docker, Docker Compose and golang development environment. Please install the below prerequisites:

| Software       | Required Version |
| -------------- | ---------------- |
| docker         | 17.05 +          |
| docker-compose | 1.18.0 +         |
| python         | 2.7 +            |
| git            | 1.9.1 +          |
| make           | 3.81 +           |
| golang\*       | 1.7.3 +          |

\*optional, required only if you use your own Golang environment.

## Step 2: Getting the source code

```sh
   $ git clone https://github.com/goharbor/harbor
```

## Step 3: Building and installing Harbor

### Configuration

Edit the file **make/harbor.yml** and make necessary configuration changes such as hostname, admin password and mail server. Refer to **[Installation and Configuration Guide](installation_guide.md#configuring-harbor)** for more info.

```sh
   $ cd harbor
   $ vi make/harbor.yml
```

### Compiling and Running

You can compile the code by one of the three approaches:

#### I. Build with official Golang image

- Get official Golang image from docker hub:

  ```sh
     $ docker pull golang:1.12.5
  ```

- Build, install and bring up Harbor without Notary:

  ```sh
     $ make install GOBUILDIMAGE=golang:1.12.5 COMPILETAG=compile_golangimage
  ```

- Build, install and bring up Harbor with Notary:

  ```sh
     $ make install GOBUILDIMAGE=golang:1.12.5 COMPILETAG=compile_golangimage NOTARYFLAG=true
  ```

- Build, install and bring up Harbor with Clair:

  ```sh
     $ make install GOBUILDIMAGE=golang:1.12.5 COMPILETAG=compile_golangimage CLAIRFLAG=true
  ```

#### II. Compile code with your own Golang environment, then build Harbor

- Move source code to \$GOPATH

  ```sh
     $ mkdir $GOPATH/src/github.com/goharbor/
     $ cd ..
     $ mv harbor $GOPATH/src/github.com/goharbor/.
  ```

- Build, install and run Harbor without Notary and Clair:

  ```sh
     $ cd $GOPATH/src/github.com/goharbor/harbor
     $ make install
  ```

- Build, install and run Harbor with Notary and Clair:

  ```sh
     $ cd $GOPATH/src/github.com/goharbor/harbor
     $ make install -e NOTARYFLAG=true CLAIRFLAG=true
  ```

### Verify your installation

If everything worked properly, you can get the below message:

```sh
   ...
   Start complete. You can visit harbor now.
```

Refer to [Installation and Configuration Guide](installation_guide.md#managing-harbors-lifecycle) for more information about managing your Harbor instance.

#### EXAMPLE:

#### Push Harbor images to specific registry server

```sh
   $ make pushimage -e DEVFLAG=false REGISTRYSERVER=[$SERVERADDRESS] REGISTRYUSER=[$USERNAME] REGISTRYPASSWORD=[$PASSWORD] REGISTRYPROJECTNAME=[$PROJECTNAME]

```

**Note**: need add "/" on end of REGISTRYSERVER. If REGISTRYSERVER is not set, images will be pushed directly to Docker Hub.

```sh
   $ make pushimage -e DEVFLAG=false REGISTRYUSER=[$USERNAME] REGISTRYPASSWORD=[$PASSWORD] REGISTRYPROJECTNAME=[$PROJECTNAME]

```

#### Clean up binaries and images of a specific version

```sh
   $ make clean -e VERSIONTAG=[TAG]

```

**Note**: If new code had been added to Github, the git commit TAG will change. Better use this command to clean up images and files of previous TAG.

#### By default, the make process create a development build. To create a release build of Harbor, set the below flag to false.

```sh
   $ make XXXX -e DEVFLAG=false

```
