# Using an Http Auth URL with git-sync

## Step 1: Create a GIT_ASKPASS HTTP Service

The GIT ASKPASS Service expose via HTTP and provide the answer to GIT_ASKPASS.

Example of the servcie's output, see more at https://git-scm.com/docs/gitcredentials

```json
username=xxx@example.com
password=ya29.mysecret
```

## Step 2: Configure git-sync container

In your git-sync container configuration, specify the GIT_ASKPASS_URL

The credentials will pass in plain text, make sure the connection between git-sync
and GIT ASKPASS Service are secure.

The recommended way is the ASKPASS Service running within the same pod as git-sync.

See https://github.com/cydu-cloud/git-askpass-gce-node as a full example which use GCE Node Service Account credential to access Google Cloud Source Repo.

```json
{
    name: "git-sync",
    ...
    env: [
        {
            name: "GIT_SYNC_REPO",
            value: "https://source.developers.google.com/p/[GCP PROJECT ID]/r/[REPO NAME]"
        }, {
            name: "GIT_ASKPASS_URL",
            value: "http://localhost:9102/git_askpass",
        },
    ...
    ]
}
```
