+## Docker
+
+### Create a Local Docker Registry with TLS
+
+On one of the VMs (e.g oahu.chopark.home), set up a local Docker registry.
+Skip if a local registry already exists.
+
+Prerequisite: Create a CA and a self-signed cert.
+
+```bash
+docker run -d --restart=always --name registry \
+  -v /opt/registry/certs:/certs \
+  -v /opt/registry/data:/var/lib/registry \
+  -e REGISTRY_HTTP_ADDR=0.0.0.0:443 \
+  -e REGISTRY_HTTP_TLS_CERTIFICATE=/certs/registry.crt \
+  -e REGISTRY_HTTP_TLS_KEY=/certs/registry.key \
+  -p 443:443 \
+  registry:2
+```
+
+### Build a Docker Image
+
+1. Create a `Dockerfile`. Refer to the `Dockerfile` in the root of this project.
+
+2. Then build the image.
+
+```powershell
+# build an image
+docker build -t catalog26 .
+
+# verify the image
+docker images | grep catalog26
+
+# also try running it
+docker run -d -p 5000:8080 -n catalog26 catalog26
+```
+
+3. Tag for my registry.
+
+```powershell
+docker tag catalog26 registry.chopark.home/catalog26
+```
+
+4. Push to Registry
+
+```powershell
+docker push registry.chopark.home/catalog26
+```
+
+Optional: If an https error is returned, make the following adjustments.
+
+On Linux, edit `/etc/docker/daemon.json`:
+
+```json
+{
+  "insecure-registries": ["registry.chopark.home"]
+}
+```
+
+On Windows (Docker Desktop):
+- Open Docker Desktop
+- Go to Settings > Docker Engine
+- Add to the JSON configuration
+
+```json
+{
+  "insecure-registries": ["registry.chopark.home"]
+}
+```
+
+## Kubernetes
+
+1. Containerd (on all K8s nodes) for https connection problem
+
+```toml
+sudo tee /etc/containerd/certs.d/registry.chopark.home/hosts.toml <<EOF
+server = "https://registry.chopark.home"
+
+[host."https://registry.choparkhome"]
+  ca = "/usr/local/share/ca-certificates/regisry.chopark.home-ca.crt"
+  skip_verify = false
+EOF
+```
+
+3. Optional Image Pull - create crictl config
+
+```bash
+# Create crictl config
+sudo tee /etc/crictl.yaml > /dev/null <<EOF
+runtime-endpoint: unix:///run/containerd/containerd.sock
+image-endpoint: unix:///run/containerd/containerd.sock
+timeout: 10
+EOF
+
+# Test crictl
+sudo crictl version
+
+# Pull image
+sudo crictl pull registry.chopark.home/catalog26
+```
