Http Tar.Gz sync

The Http tar.gz sync allows an application to fetch policies and data from a tar.gz file located on a http server. The implementation tries to stay close to OPA Server implementation.

To add the tar.gz sync to your application, add the following:

services.AddOpa(opt =>
  .AddSync(s =>
    s.UseHttpTarGz(opt =>
    {
      opt.Url = new Uri("https://yourserver");
    })
  )
);

Adding headers

If you need to add custom headers to the request you can do that by adding them to the Headers property under the options:

services.AddOpa(opt =>
  .AddSync(s =>
    s.UseHttpTarGz(opt =>
    {
      opt.Url = new Uri("https://yourserver");
      opt.Headers.Add("custom", "value");
    })
  )
);

OAuth2 Support

If the service requires an OAuth2 access token, it is possible to configure the sync to authorize against an OAuth2 server. The only supported grant type at this point is client_credential.

Example:

services.AddOpa(opt =>
  .AddSync(s =>
    s.UseHttpTarGz(opt =>
    {
      opt.Url = new Uri("https://yourserver");
      opt.UseOAuth2(auth =>
      {
        auth.ClientId = "clientid";
        auth.ClientSecret = "client secret";
        auth.TokenUrl = "https://tokenurl";
        auth.Scopes = new List<string>() { "scope" };
      });
    })
  )
);
