cobli/ubuntu-init-14-04

Base: ubuntu-upstart:14.04

Ubuntu 14.04 (Trusty) image with Upstart 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).

• curl
• git
• vim
• some network tools

cobli/ubuntu-init-16-04

Base: ubuntu:16.04 Ubuntu 16.04 (Xenial) image with systemd as an init service. Similar to the 14.04 image, but with 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
• seccomp must be set to unconfined
• 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-python-14-04

Base: ubuntu-init-14-04

Adds Python 2 development packages and some dependencies commonly used for building Python packages.

cobli/ubuntu-init-python-16-04

Base: ubuntu-init-16-04

Same as above, but for Ubuntu 16.04.

cobli/jdk11-datadog-agent

Base: openjdk:11.0.16-jre-slim-buster

This is a Java image with the datadog agent configured

It downloads the datadog agent and adds it to the JAVA_OPTS environment variable. You can override the JAVA_OPTS, but remember to configure the agent by adding the parameter: -javaagent:/opt/java-app/dd-java-agent.jar.

To configure the DataDog agent, you need to set its environment variables. For example:

• DD_ENV: prod
• DD_TRACE_ENABLED: "false"
• DD_AGENT_HOST: ${YOUR_AGENT_HOST_URL}
• DD_SERVICE: ${YOUR_SERVICE_NAME}
