## Build and install
## Using cri-dockerd

### Install

The easiest way to install `cri-dockerd` is to use one of the pre-built binaries or
packages from the [releases page](https://github.com/Mirantis/cri-dockerd/releases).
There are numerous supported platforms and using a pre-built package will install
the binary and setup your system to run it as a service.

Please refer to your platform's documentation for how to install a package for
additional help with these.

## Advanced Setup

### Installing manually

To begin following the build process for this code, clone this repository in your local environment:
> Note: the release packages will install to /usr/bin which is reserved for
> binaries managed by a package manager. Manual installation doesn't involve a
> package manager and thus uses /usr/local/bin and the service file must be edited
> to reflect this.
If you would like to install the project manually, you will need to place the binary
somewhere in your `PATH` and setup a service to run it. The following command is
a manual install for a Linux system using systemd:

```shell
git clone https://github.com/Mirantis/cri-dockerd.git
```

The above step creates a local directory called ```cri-dockerd``` which you will need for the following steps.

## To use with Kubernetes
### To use with Kubernetes

The default network plugin for `cri-dockerd` is set to `cni` on Linux. There are
a few ways to change this depending on how you are running the binary.

`--network-plugin=${plugin}` can be passed in as a command line argument when
- running the binary directly
- adding to `/usr/lib/systemd/system/cri-docker.service` if a service isn't enabled
- adding to `/etc/systemd/system/multi-user.target.wants/cri-docker.service` if a service is enabled

Run `systemctl daemon-reload` to restart the service if it was already running.

## Development

### Building

If you would like to build the project yourself, you will need to have Go installed.
You can find directions for installing the latest version on its website:

[Install the latest version of Go](https://golang.org/doc/install)

Once you have Go installed, you can build the project by running the following command:

```shell
make cri-dockerd
```

This will output the binary to the project's root directory as `cri-dockerd`.
You can then run it directly or install it using the manual process above.

To build for a specific architecture, add `ARCH=` as an argument, where `ARCH`
is a known build target for Go.

```shell
ARCH=amd64 make cri-dockerd
```

### Development Setup

When developing, it is nice to have a separate environment to test in so that
you don't have to worry about breaking your system. An easy way to do this is
by setting up a minikube cluster since it uses `cri-dockerd` by default. Follow
the [minikube installation instructions](https://minikube.sigs.k8s.io/docs/start/)
to get it installed.

You'll then be able to create a cluster in minikube's VM by running:

```shell
minikube start
```

Once the cluster is up, we have a `make` command that will build `cri-dockerd`
and swap it out for the version running in the cluster. You can run this command
by running:

```shell
make dev
```

## Docs

This folder contains the files used to generate the `cri-dockerd` documentation.

The docs are generated using [Hugo](https://gohugo.io/) and the [Geekdocs](https://themes.gohugo.io/hugo-geekdoc/) theme.

### Editing Docs

The docs can be ran locally with hot-reloading to make editing easier. To do so,
run the following command in the project's root directory:

```bash
make docs
```

The default network plugin for `cri-dockerd` is set to `cni` on Linux. To change this, `--network-plugin=${plugin}`
can be passed in as a command line argument if invoked manually, or the systemd unit file
(`/usr/lib/systemd/system/cri-docker.service` if not enabled yet,
or `/etc/systemd/system/multi-user.target.wants/cri-docker.service` as a symlink if it is enabled) should be
edited to add this argument, followed by `systemctl daemon-reload` and restarting the service (if running)
This will launch the development server that is included with Hugo. You can then
access the docs at http://localhost:1313/

Mirantis and Docker have agreed to partner to maintain the shim code standalone outside Kubernetes, as a conformant CRI
interface for the Docker Engine API. This means that you can continue to build Kubernetes
based on the Docker Engine as before, just switching from the built in dockershim to the external one.

Mirantis and Docker intend to work together on making sure it continues to work as well as before and that it
passes all the conformance tests and continues to work just like the built in version did. Mirantis will be using
this in Mirantis Kubernetes Engine, and Docker will continue to ship this shim in Docker Desktop. For Mirantis customers,
this means that Docker Engine’s commercially supported version, Mirantis Container Runtime (MCR), will be CRI compliant.

You can find more information about the context for this
tool in [Don't Panic: Kubernetes and Docker](https://blog.k8s.io/2020/12/02/dont-panic-kubernetes-and-docker/)
and on the Mirantis
[blog](https://www.mirantis.com/blog/mirantis-to-take-over-support-of-kubernetes-dockershim-2/).

These are the steps in order to create a new release for `cri-dockerd`. These steps will need to be done by a project maintainer.

1. Setup the repo for a new release
1. Change the version found in `VERSION`, `cmd/version/version.go`, and `packaging/common.mk` to the new version
2. Create a PR with these changes and merge them to master
3. Build the release artifacts using `make release`
4. Verify the artifacts in the `build/release` directory and make sure they look correct
2. A maintainer creates a new draft release in the project's [releases section](https://github.com/Mirantis/cri-dockerd/releases)
1. The name should follow semantic convention prepended with a 'v'
2. A tag with the same name should be created on the latest commit to master from the previous step
3. Release notes should be generated using the previous tag and the new tag as the range
4. Check the box to **Set as a pre-release**
5. Upload the release artifacts from the previous step
5. Save as a draft
3. The release can now go through a review process to look for any issues
4. Change the draft to a published release
5. Celebrate :cheers:
