Dockerfile

FROM ubuntu:bionic

ENV DEBIAN_FRONTEND=noninteractive

# tools you need to build MRI
RUN apt-get update && apt-get install -y tzdata git ruby autoconf bison gcc make zlib1g-dev libffi-dev libreadline-dev libgdbm-dev libssl-dev build-essential

You may want to add

ENV DEBIAN_FRONTEND=noninteractive

RUN apt-get install -y tzdata

to Dockerfile when encounter fails during make check for timezone related tests.

For network-related tests that may fail, you can enable ipv6 for docker by editing /etc/docker/daemon.json

{
    "ipv6": true,
    "fixed-cidr-v6": "2001:db8:1::/64"
}

restart docker daemon with # systemctl reload docker.service, then enable ipv6 on your container add this on docker-compose.yml

sysctls:
  - net.ipv6.conf.all.disable_ipv6=0
