# Replacing Docker Desktop with Colima

It allows us to keep using docker and docker-compose normally, which is good for legacy scripts.

===

## Installation

1) Uninstall Docker Desktop 

2) Install the things that were provided by Docker Desktop 
`brew install docker docker-compose kubectl`

3) Install Colima
`brew install colima` 

===

## Configuration

Start Colima for the 1st time to change defaults
`colima start --edit`

Change these configs to match Docker Desktop's 
```
cpu: 4
memory: 4
autoActivate: false
```

Tell docker to use the colima context
`docker context use colima`

...or add the following environment variable
`export DOCKER_HOST=unix://$HOME/.colima/default/docker.sock`

That's all! docker and docker-compose should work normally 

The configs can be changed as many times as you want, you just need to stop colima first 
`colima stop`

===

## Usage

`colima start`

{{ do stuff with docker/docker-compose }}

`colima stop`

// to check colima's status at any time 
`colima status`
