cobli/ubuntu-init-python3 repository overview

⁠Cobli CI Images

This repository contains specifications for some Docker images used in Continuous Integration of other Cobli projects.

⁠cobli/ubuntu-init:18-04

Base: ubuntu:18.04 Ubuntu 18.04 (Bionic Beaver) image with systemd as an init system. A test user is created, and OpenSSH is set up to access it (either by setting a password or adding some authorized keys with docker exec). Additionally contains:

• sudo
• dbus
• curl
• git
• vim
• some network tools

This docker file needs some additional requirements for running it, since systemd needs some system privilegs to run.

• /sys/fs/cgroup must be bind-mounted (possibly RO) from the host system
• CAP_SYS_ADMIN must be granted
• Three tmpfs mounts must be set up:
  • /tmp:exec,mode=1777
  • /run
  • /run/lock
• stop_signal must be set to SIGRTMIN+3

⁠cobli/ubuntu-init-python3:18-04

Base: ubuntu-init:18-04

Adds Python 3 development packages and some dependencies commonly used for building Python packages.
