inter-host tunneling, with encryption

OCI Tools 2019 docker-slim

performs simple runtime analysis to remove unnecessary libraries and slim down images

2018 buildah

Orchestration 2015 Kubernetes

The current industry favorite


Still arguably one of the nicer options in 2018

Other runtimes 2022 nerdctl

can be used to manage containers in containerd/k3s

2019 podman

aims for 1:1 CLI parity (see also Buildah and Skopeo)

2018 Singularity

a different take on containers, not quite OCI compliant

PaaS 2020 CapRover

a nice web front-end for Docker Swarm

Tools 2024 lazydocker

a nice TUI for Docker management, with usage charts and easy stack/compose viewing (Portainer for terminals)

2023 distrobox

a nice wrapper for sandbox management


a macOS VM container manager that replaces Docker desktop and works well with brew.

Setting up boot2docker manually on Parallels

Since I don’t have Parallels Pro, I run Docker on my older Macs like this:

  • Download a recent release and put the ISO someplace safe
  • Create a new VM manually by dragging the ISO to Parallels (use the Shared or NAT network type)
  • After first boot, use fdisk to create a primary partition in /dev/sda and format it using mkfs.ext4 -L boot2docker-data /dev/sda1
  • Reboot so that it gets mounted and used for certificate storage
  • Do brew install docker (which gets you the CLI)
  • Set up port forwarding for port 2376 and a local port to the VM’s SSH port
  • SSH into the VM (docker/tcuser) and copy the *.pem files from /var/lib/boot2docker/tls to your ~/.docker folder
  • Set and export DOCKER_HOST and DOCKER_TLS_VERIFY accordingly:
export DOCKER_HOST=localhost:2376

Useful Dockerfile Snippets

Base Image Description Dockerfile snippet
Ubuntu Installing the Oracle JDK (and setting the EULA)
RUN echo oracle-java8-installer shared/accepted-oracle-license-v1-1 select true | debconf-set-selections \
 && add-apt-repository -y ppa:webupd8team/java \
 && apt-get install -y java-common oracle-java8-installer oracle-java8-set-default \
 && rm -rf /var/cache/oracle-jdk8-installer

Building The Docker Registry From Scratch (on ARM, too!)

Very simple, really, once you have installed. Quite quick on a 2, too:

export GOPATH=$HOME/go
export PATH=$GOPATH/bin:$PATH
# this fetches godep and golint
go get
# this fetches and builds the registry
go get
# test it with the default config
$GOPATH/bin/registry $GOPATH/src/
