Running a basic container

This guide will walk you through the steps of running a very basic container on a worker node.

Step 1: Reserve a worker node

See the “reservation of a worker node” section.

Step 2: Create a container

  • From the ExPECA home page, click Container -> Containers

Containers main page

  • Click + Create Container

  • Under Info tab, give the container a name of your choosing, which can NOT contain the “underscore” (_) character

  • Type “alpine” as image name (or a Docker hub image of your choosing)

Create container, first screen

  • Under Scheduler Hints tab, add “reservation” as hint

Create container, second screen

  • Paste the “reservation ID” for the worker node lease you have created. Note that the “reservation ID” can be obtained from Reservations -> Leases -> click on your lease.

  • Now click on Create to create your container. After a short time, the container is created, and by default should be running.

Running container

  • Click on your container and then on the Console tab. You then have an interactive console where you can give commands in your container. It is created from a Linux image, so basic Linux commands are available.
