Docker on Windows

Ubuntu on WSL

First make sure uninstall all of the old Ubuntu installation under App & Features.

Install Windows Subsystem for Linux under App & Features > Optional features > More Windows features, then

wsl --update
wsl --set-default-version 2
wsl --install Ubuntu

Under Ubuntu terminal, create your root account then

Add proxy for apt

cat << EOF | sudo tee -a /etc/apt/apt.conf.d/proxy.conf
Acquire::http::Proxy "http://myproxy.com:8080/";
EOF

Add proxy for curl

cat << EOF | sudo tee -a /etc/profile.d/http-proxy.sh
export http_proxy="http://myproxy.com:8080/"
export https_proxy="http://myproxy.com:8080/"
export no_proxy="localhost,127.0.0.1,localaddress,.localdomain.com"
EOF

Install docker

sudo apt update
sudo apt install docker.io -y

Add proxy for docker

sudo mkdir /etc/systemd/system/docker.service.d
cat << EOF | sudo tee -a /etc/systemd/system/docker.service.d/http-proxy.conf
[Service]
Environment="HTTP_PROXY=http://myproxy.com:8080/"
Environment="HTTPS_PROXY=http://myproxy.com:8080/"
Environment="NO_PROXY=localhost,127.0.0.1,localaddress,.localdomain.com"
EOF

Add insecure registry

cat << EOF | sudo tee -a /etc/docker/daemon.json
{
  "insecure-registries" : [ "myregistry.com:5000" ]
}
EOF

Add config for registry

cat << EOF | sudo tee -a /etc/profile.d/registry.sh
export REGISTRY_USER=xxxx
export REGISTRY_TOKEN=xxxx
EOF

Restart docker

sudo service docker restart

Use docker

Allow local user to run docker without sudo

sudo usermod -aG docker $USER
sudo chown root:docker /var/run/docker.sock
exit

Open a Command Prompt then run wsl, you can now use docker as normal.

Install kubectl

sudo apt update
sudo apt install -y apt-transport-https ca-certificates curl
curl -fsSL https://pkgs.k8s.io/core:/stable:/v1.28/deb/Release.key | sudo gpg --dearmor -o /etc/apt/keyrings/kubernetes-apt-keyring.gpg
echo 'deb [signed-by=/etc/apt/keyrings/kubernetes-apt-keyring.gpg] https://pkgs.k8s.io/core:/stable:/v1.28/deb/ /' | sudo tee /etc/apt/sources.list.d/kubernetes.list

sudo apt update
sudo apt install -y kubectl

cat << EOF | sudo tee -a /etc/profile.d/kubectl.sh
alias k='kubectl'
alias kn='kubectl config set-context --current --namespace '
alias kc='kubectl config use-context '
EOF

Install kind

curl -Lo ./kind https://kind.sigs.k8s.io/dl/v0.20.0/kind-linux-amd64
chmod +x ./kind
sudo mv ./kind /usr/local/bin/kind

Create Cluster

cat << EOF >> cluster-config.yml
# cluster-config.yml
kind: Cluster
apiVersion: kind.x-k8s.io/v1alpha4
nodes:
- role: control-plane
  extraPortMappings:
  - containerPort: 30000
    hostPort: 30000
    protocol: TCP
EOF

kind create cluster --config=cluster-config.yml

Teardown

wsl --shutdown
wsl --unregistry Ubuntu

Podman on WSL

First install Windows Subsystem for Linux, then

choco install podman-cli podman-desktop -y

Add insecure registry

Open Podman Desktop then Goto Settings > Registries > Add registry

• Location: myregistry.com:5000

Ssh into podman machine

podman machine ssh
> sudo vi /etc/containers/registries.conf

then append the following to the end of file

[[registry]]
location = "myregistry.com:5000"
insecure = true

finally restart the podman machine

podman machine stop
podman machine start

You can now use podman to replace docker.

Teardown

podman machine stop
podman machine rm
choco uninstall podman-cli podman-desktop -y
