• linuxkit

  15 8,244 9.1 Go

  A toolkit for building secure, portable and lean operating systems for containers

  

  Note: Namespaces are a feature of the linux kernel. But Docker allows you to run containers on Windows and Mac... how does that work? The secret is that embedded in the Docker product or Docker engine is a linux subsystem. Docker open-sourced this linux subsystem to a new project: LinuxKit. Being able to run containers on many different platforms is one advantage of using the Docker tooling with containers.

• podman

  369 22,995 10.0 Go

  Podman: A tool for managing OCI containers and pods.

  

  What makes containers useful is the tooling that surrounds it. For these labs, we will be using Docker, which has been a widely adopted tool for using containers to build applications. Docker provides developers and operators with a friendly interface to build, ship and run containers on any environment with a Docker engine. Because Docker client requires a Docker engine, an alternative is to use Podman, which is a deamonless container engine to develop, manage and run OCI containers and is able to run containers as root or in rootless mode. For those reasons, we recommend Podman but because of adoption, this lab still uses Docker.

• mongo

  6 1,028 8.7 Shell

  Docker Official Image packaging for MongoDB (by docker-library)

  

  One thing you might notice is that the mongo container is running the docker-entrypoint command. This is the name of the executable that is run when the container is started. The mongo image requires some prior configuration before kicking off the DB process. You can see exactly what the script does by looking at it on github. Typically, you can find the link to the github source from the image description page on the Docker Store website.

  Source repo for Docker's Documentation (by docker)

  

  We will be using a few Docker commands in this lab. For full documentation on available commands check out the official documentation.
