curl | sh is a bad practice, but lack of "curl https://get.docker.com | sh" scenario is certainly bad for Podman adoption.

sudo apt-get purge docker-ce docker-ce-cli containerd.io docker-buildx-plugin docker-compose-plugin docker-ce-rootless-extras sudo rm -rf /var/lib/docker sudo rm -rf /var/lib/containerd Install Docker curl -fsSL https://get.docker.com -o get-docker.sh sudo sh ./get-docker.sh

For Linux (using curl): curl -fsSL https://get.docker.com -o get-docker.sh && sh get-docker.sh

Install Docker (curl -sSL https://get.docker.com/ | sudo sh)

On WSL2, you just install Docker the same way as you would do on Linux. `sudo apt install docker.io` (from Debian/Ubuntu repo) or `curl https://get.docker.com | sh` (from Docker Inc). If you are using different WSL distribution, the standard way to install docker should work just fine. (e.g. `sudo pacman -S docker` works as expected on ArchWSL)

curl https://get.docker.com | bash -E

After all the resources are provisioned, I need to install Docker and pull a specific image. I will install Docker like this: curl -sSL https://get.docker.com | sh.

# 1. download the script # # $ curl -fsSL https://get.docker.com -o install-docker.sh # # 2. verify the script's content # # $ cat install-docker.sh # # 3. run the script with --dry-run to verify the steps it executes # # $ sh install-docker.sh --dry-run # # 4. run the script either as root, or using sudo to perform the installation. # # $ sudo sh install-docker.sh #

If you don't need a GUI, the following combo works pretty well:

You might look into CoLima as a way to get started.

Its user interface is Docker-like, using containers.

For full desktop, I've only used the commercial app "Parallels", which can set up an Ubuntu desktop for you. Also Fedora and Alpine and Debian I believe.

But

> I don't really have any resources to share. I just know how to boot a vmlinuz with an initramfs using QEMU, and decided to download the Linux kernel source code and try compiling it.

I highly recommend working through Linux from Scratch and possibly the Gentoo Handbook. It's a journey.

I could not find any guide how to add WASM container capability to Docker running on Colima. This guide provides a few Colima templates for exactly this, which adds WasmEdge, Wasmtime and Wasmer runtime types.

Colima runs much faster on Macos: https://github.com/abiosoft/colima

After docker desktop became unusable, I jumped to colima and never looked back. I still use the docker runtime in it (the non-proprietary part) but it also supports containerd. On Mac it's just a "brew install colima" and then "colima start"

I also install the compose and ecr credentials plug-ins (since I use ecr for my container registry.) It has the full functionality of docker desktop minus the UI, which I never used anyways.

On my M1 Pro system, I have nothing but positive things to say about the experience of using Colima (https://github.com/abiosoft/colima). Quick to set up and fast to use.

I'd say Lima and Colima should be enough for most use cases:

The bash/zsh equivalent wouldn't be too hard, but I use fish.

[3] I’m on OrbStack now, but it isn’t so much better at how I use Docker than Colima is that I think that it’s an instant buy, especially with the planned subscription model. If I used anything other than the Docker integration, I might think it's better, but as of right now, no.

I also have some issues with its insistence on asking for elevated permissions. I will never grant permission[4] to make a symlink to the "standard" Docker socket; context and `$DOCKER_HOST` work well enough. It should not ask if the permission hasn't been given once. I also worry about other "advanced" features that may need an elevated permissions helper[5].
