### Prerequisites
* Windows:
* [Docker Desktop](https://hub.docker.com/editions/community/docker-ce-desktop-windows)
* make
* macOS:
* [Docker Desktop](https://hub.docker.com/editions/community/docker-ce-desktop-mac)
* make
* Linux:
* [Docker 19.03 or later](https://docs.docker.com/engine/install/)
* make
### Building the CLI
Once you have the prerequisites installed, you can build the CLI using:
```console
make
```
This will output a CLI for your host machine in `./bin`.
You will then need to make sure that you have the existing Docker CLI in your
`PATH` with the name `com.docker.cli`. A make target is provided to help with
this:
```console
make moby-cli-link
```
This will create a symbolic link from the existing Docker CLI to
`/usr/local/bin` with the name `com.docker.cli`.
You can statically cross compile the CLI for Windows, macOS, and Linux using the
`cross` target.
### Updating the API code
The API provided by the CLI is defined using protobuf. If you make changes to
the `.proto` files in [`protos/`](./protos), you will need to regenerate the API
code:
```console
make protos
```
### Unit tests
To run all of the unit tests, run:
```console
make test
```
If you need to update a golden file simply do `go test ./... -test.update-golden`.
### End to end tests
#### Local tests
To run the local end to end tests, run:
```console
make e2e-local
```
Note that this requires the CLI to be built and a local Docker Engine to be
running.
#### ACI tests
To run the end to end ACI tests, you will first need to have an Azure account
and have created a service principal. You can create a service principle using
the Azure CLI after you have done a `docker login azure`:
```console
$ docker login azure
$ az ad sp create-for-rbac --name 'MyTestServicePrincipal' --sdk-auth
```
You can then run the ACI tests using the `e2e-aci` target with the various
`AZURE_` environment variables set:
```console
AZURE_TENANT_ID="xxx" AZURE_CLIENT_ID="yyy" AZURE_CLIENT_SECRET="yyy" make e2e-aci
```
Running the ACI tests will override your local login and the service principal
credentials use a token that cannot be refreshed automatically.
*Note:* You will need to rerun `docker login azure` if you would like to use the
CLI after running the ACI tests.
You can also run a single ACI test by specifying the test name with the
`E2E_TEST` variable:
```console
AZURE_TENANT_ID="xxx" AZURE_CLIENT_ID="yyy" AZURE_CLIENT_SECRET="yyy" make E2E_TEST=TestContainerRun e2e-aci
```
#### ECS tests
To run the end to end ECS tests, you will need to have an AWS account and have
credentials for it in the `~/.aws/credentials` file.
You can then use the `e2e-ecs` target:
```console
TEST_AWS_PROFILE=myProfile TEST_AWS_REGION=eu-west-3 make e2e-ecs
```
## Releases
To create a new release:
* Check that the CI is green on the main branch for commit you want to release
* Create a new tag of the form vx.y.z, following existing tags, and push the tag
Pushing the tag will automatically create a new release and make binaries for
Windows, macOS, and Linux available for download on the
[releases page](https://github.com/docker/compose-cli/releases).
