+# Kreeger's devcontainer
+
+A devcontainer build that I use as the base for all my dev work.
+
+## Building locally
+
+Make sure you have the prerequisites installed. For me this meant BuildX and
+BuildKit for Docker.
+
+```bash
+$ brew install docker-buildx
+$ brew install buildkit
+$ VERSION=$(curl https://api.github.com/repos/docker/buildx/releases/latest -s | jq .name -r)
+$ ARCH=arm64
+$ curl -LO https://github.com/docker/buildx/releases/download/${VERSION}/buildx-${VERSION}.darwin-${ARCH}
+$ mkdir -p ~/.docker/cli-plugins
+$ mv buildx-${VERSION}.darwin-${ARCH} ~/.docker/cli-plugins/docker-buildx
+$ chmod +x ~/.docker/cli-plugins/docker-buildx
+$ docker buildx version
+```
+
+Login to Gitea.
+
+```bash
+$ docker login git.kree.gr
+```
+
+And then build the thing.
+
+```bash
+$ DOCKER_BUILDKIT=1 devcontainer build --workspace-folder . \
+      --push true --image-name \
+      git.kree.gr/kreeger/devcontainer:${$(git rev-parse HEAD):-8}
+```
