HOW TO Replacing Docker Desktop with Colima.md

Run docker in macos without docker desktop

and suggestions from my colleagues ❤️

Prepare

Stop Docker.
Delete Docker.app.

Run brew doctor and update to make sure everything is working and up to date

Prerequisite : have brew installed on your mac https://brew.sh/

$ brew doctor
$ brew update

Install Docker CLI

$ brew install docker
$ brew install docker-compose

Install Colima

via Homebrew

$ brew install colima

see more options here : https://github.com/abiosoft/colima#getting-started

Configure mem and cpu

$ colima start --cpu 4 --memory 8

You should now be good to go : docker and docker-compose now work as usual

Troubleshooting

failed to solve: XXXXX/YYYYYYYYY: failed to do request: Head "XXXXX/YYYYYYYYY": dial tcp: lookup registry-1.docker.io on 192.168.107.1:53: read udp 192.168.5.15:56530->192.168.107.1:53: i/o timeout

You may need to log in to a registry to pull an image https://docs.docker.com/engine/reference/commandline/login/

$ docker login

Tip #1

Try this when colima start fails (assuming it worked in the past)

$ colima stop -f
$ colima start

Tip #2

If you get this error

error getting credentials - err: exec: "docker-credential-desktop": executable file not found in $PATH, out: ``

Try this: In ~/.docker/config.json change credsStore to credStore
source: https://forums.docker.com/t/docker-credential-desktop-exe-executable-file-not-found-in-path-using-wsl2/100225/5

for Tip #2 I believe this command will work sed 's/credsStore/credStore/g' ~/.docker/config.json > ~/.docker/config2.json && mv -f ~/.docker/config2.json ~/.docker/config.json

If we just edit installer.mac to include this instead of saying "docker not found" it should install automatically:

# Create and provision using docker
# Check for docker
if [ -z $(which docker) ]; then
    echo "Docker missing, will install it before proceeding"
    brew doctor
    brew update
    brew install docker
    brew install docker-compose
    brew install colima
    colima start --cpu 4 --memory 8
    # fix error:
    sed 's/credsStore/credStore/g' ~/.docker/config.json >  ~/.docker/config2.json && mv -f ~/.docker/config2.json ~/.docker/config.json
fi
cp docker-compose.mac.yml docker-compose.override.yml

#if [ ! -f .env_local ]; then
echo "Creating .env_local for local environment using .env_default settings"
cp .env_default .env_local
