Manage containers, pods, and images with Podman. Seamlessly work with containers and Kubernetes from your local environment.

# MACHINE
podman machine init
podman machine init --cpus 4 --memory 8192 --disk-size 20
podman machine start

# IMAGES
podman image list 
podman image rm <ID>
podman build -t skobba/frontend:latest .
time podman build -t skobba/reactapp:latest . --log-level=debug

# CONTAINERS
podman container ps -a
podman container rm <ID>

# Start Postgres
podman run --name skobba_postgres -e POSTGRES_PASSWORD='qwe123' -d -p 5432:5432 postgres:13.8

# Copy file
podman cp db_dump.sql skobba_postgres:/db_dump.sql

# Container shell
podman exec -it skobba_postgres bash
podman exec skobba_postgres pg_restore -U postgres -d skobba /database_dump

Pods

podman pod create --label myFirstPod
podman pod create --label mySecondPod
podman pod ps

podman play kube some-mariadb.yaml

Create unix socket

podman-mac-helper

  1. Install helper 
    sudo podman-mac-helper install
  2. Restart podman machine outputs: 
    Starting machine "skobbis"
Waiting for VM ...
Mounting volume... /Users:/Users
Mounting volume... /private:/private
Mounting volume... /var/folders:/var/folders
API forwarding listening on: /var/run/docker.sock
Docker API clients default to this address. You do not need to set DOCKER_HOST.
Machine "skobbis" started successfully
  3. Verify that socket file was created 
    ls -la /var/run/docker.sock

DOCKER_HOST

export DOCKER_HOST=unix:///run/user/1000/podman/podman.sock

export DOCKER_HOST=ssh://core@127.0.0.1:53473/run/user/1412831964/podman/podman.sock

Connection list

podman system connection list

Build context

If a build context is not specified, and at least one Containerfile is a local file, the directory in which it resides is used as the build context.

Slow build time

Install fuse-overlayfs

brew install fuse-overlayfs
podman system reset
podman info

Switch from docker

echo alias docker=podman >> ~/.zshrc
sudo rm -rf  /usr/local/bin/docker
sudo ln -s /usr/local/bin/podman /usr/local/bin/docker || true

Azure Container Registry Login

Get credentials:
