Authentication / Personal Access Tokens / access.yaml

In order to consume private git repositories, Fabrikate facilitates the use of environment variables containing personal access tokens in an access.yaml file which lives in the root of your component along side your component.yaml.

If this access.yaml file is present in the root component you call fab install on, any components installed (whether in the root component or any nested subcomponent) which have a matching source attribute to any of the keys found in the access.yaml map will use the value contained in the corresponding env variable as a PAT for authentication.

access.yaml

The access.yaml file is a flat mapping of Component source strings to environment variable.

A sample could look like this:

my-component/component.yaml:

name: my-private-component
method: git
source: https://github.com/microsoft/my-private-git-repo
subcomponents:
  - name: another-private-component
    method: git
    source: https://github.com/microsoft/another-private-git-repo
  - name: one-more-private-component
    method: git
    source: https://github.com/microsoft/once-more-private-git-repo

my-component/access.yaml:

https://github.com/microsoft/my-private-git-repo: ENV_VAR_CONTAINING_MY_PAT
https://github.com/microsoft/another-private-git-repo: ANOTHER_ENV_VAR
https://github.com/microsoft/once-more-private-git-repo: ANOTHER_ENV_VAR

Unless ENV_VAR_CONTAINING_MY_PAT and ANOTHER_ENV_VAR are set to the correct tokens in your env, fab install will fail. Fabrikate will still attempt to clone the repos and log warnings that the env vars are missing; however if they are actually private, it will fail and exit with an authentication error.

Replacing <token> with the appropriate values, the following will work:

ENV_VAR_CONTAINING_MY_PAT=<token> \
ANOTHER_ENV_VAR=<token> \
fab install

Subcomponents specifying access.yaml

Any subcomponent in your component tree can also specify an access.yaml. This is important to note when consuming other components which may specify private repositories. If this occurs, the best way to debug any missing env vars is to run fab install and look at the warning logs to see which components are asking for which variables and tokens (missing env vars will be logged as warnings during install).
