# Kubernetes Agent repository overview **(PREMIUM SELF)**
|
|
|

## `build`
|
|
|
|
Various files for the build process.
|
|
|
|
### `build/deployment`
|
|
|
|
A [`kpt`](https://googlecontainertools.github.io/kpt/) package that bundles some
|
|
[Kustomize](https://kustomize.io/) layers and components. Can be used as-is, or
|
|
to create a custom package to install `agentk`.
|
|
|
|
## `cmd`
|
|
|
|
Commands are binaries that this repository produces. They are:
|
|
|
|
- `kas` is the GitLab Kubernetes Agent Server binary.
|
|
- `agentk` is the GitLab Kubernetes Agent binary.
|
|
|
|
Each of these directories contain application bootstrap code for:
|
|
|
|
- Reading configuration.
|
|
- Applying defaults to it.
|
|
- Constructing the dependency graph of objects that constitute the program.
|
|
- Running it.
|
|
|
|
### `cmd/agentk`
|
|
|
|
- `agentk` initialization logic.
|
|
- Implementation of the agent modules API.
|
|
|
|
### `cmd/kas`
|
|
|
|
- `kas` initialization logic.
|
|
- Implementation of the server modules API.
|
|
|
|
## `examples`
|
|
|
|
Git submodules for the example projects.
|
|
|
|
## `internal`
|
|
|
|
The main code of both `gitlab-kas` and `agentk`, and various supporting building blocks.
|
|
|
|
### `internal/api`
|
|
|
|
Structs that represent some important pieces of data.
|
|
|
|
### `internal/gitaly`
|
|
|
|
Items to work with [Gitaly](../../administration/gitaly/index.md).
|
|
|
|
### `internal/gitlab`
|
|
|
|
GitLab REST client.
|
|
|
|
### `internal/module`
|
|
|
|
Modules that implement server and agent-side functionality.
|
|
|
|
### `internal/tool`
|
|
|
|
Various building blocks. `internal/tool/testing` contains mocks and helpers
|
|
for testing. Mocks are generated with [`gomock`](https://pkg.go.dev/github.com/golang/mock).
|
|
|
|
## `it`
|
|
|
|
Contains scaffolding for integration tests. Unused at the moment.
|
|

## `pkg`
|
|
|
|
Contains exported packages.
|
|
|
|
### `pkg/agentcfg`
|
|
|
|
Contains protobuf definitions of the `agentk` configuration file. Used to configure
|
|
the agent through a configuration repository.
|
|
|
|
### `pkg/kascfg`
|
|
|
|
Contains protobuf definitions of the `gitlab-kas` configuration file. Contains an
|
|
example of that configuration file along with the test for it. The test ensures
|
|
the configuration file example is in sync with the protobuf definitions of the
|
|
file and defaults, which are applied when the file is loaded.
