Install
brew install --cask orbstack
[!NOTE] After install, when you open for first time, It will need admin access to finish setup.
It will also add following lines to ~/.zprofile
# Added by OrbStack: command-line tools and integration
# This won't be added again if you remove it.
source ~/.orbstack/shell/init.zsh 2>/dev/null || :
Usage
orb logs docker
orb config show
docker context show
orb restart docker
orb migrate docker
# If you're running low on disk space, you can clear the cache manually:
docker builder prune -a
Side-by-side
# Switch to OrbStack
docker context use orbstack
# Switch to Docker Desktop
docker context use desktop-linux
(Optional) Add docker registry mirror if needed in Corp env:
brew install kubectx # to switch kube context, namespace quickly. https://github.com/ahmetb/kubectx
brew install kubens # to switch kube quickly
brew install kubernetes-helm # package manager for Kubernetes
brew install kustomize # Kubernetes native configuration management
brew install stefanprodan/tap/kustomizer # package manager for distributing Kubernetes configuration as OCI artifacts
brew install derailed/k9s/k9s # Manage Your k8s In Style!
brew install istioctl # Istio configuration command line utility
brew install dive # A tool for exploring a docker image, layer contents, and discovering ways to shrink the size of your Docker/OCI image
brew install crane # A tool for interacting with remote images and registries.
brew tap anchore/syft && brew install syft # SBOM tool
brew install cosign # Container Signing, Verification and Storage in an OCI registry.
brew install skaffold # build and deploy docker images
go install sigs.k8s.io/bom/cmd/bom@latest # Create SPDX-compliant Bill of Materials
Usage
docker info
docker version
docker stats
docker context list
# to use tools like dive, you may need to switch context to docker-desktop
docker context use docker-desktop
docker top CONTAINER
docker volume ls
docker network ls
docker system prune -a
docker system df
# List builder instances
docker buildx ls
# inspect current builder instance
docker buildx inspect
docker buildx imagetools inspect <MULTI_PLATFORM_IMAGE>
docker buildx imagetools inspect --raw nginx:alpine | jq

Sign the container image while pushing:
# Sign the image with Keyless mode
docker push --sign=cosign devopps/hello-world
# Sign the image and store the signature in the registry
docker push --sign=cosign --cosign-key cosign.key devopps/hello-world
Verify the container image while pulling:
# Verify the image with Keyless mode
docker pull --verify=cosign devopps/hello-world
# push first
docker push -ghcr.io/xmlking/grpc-starter-kit/base:v0.2.0
# then sigh and verify
COSIGN_EXPERIMENTAL=1 cosign sign ghcr.io/xmlking/grpc-starter-kit/base:v0.2.0
COSIGN_EXPERIMENTAL=1 cosign verify ghcr.io/xmlking/grpc-starter-kit/base:v0.2.0
Generate and upload the SBOM
We will use the syft to generate the SBOM and once its generated we will attach to image using cosign
# Let’s first generate the SBOM
syft packages ghcr.io/junaid18183/sampleapp:0.0.1 -o spdx > latest.spdx
cosign attach sbom --sbom latest.spdx ghcr.io/xmlking/sampleapp:0.0.1
Dive
To explore docker image layers:
