Install ubuntu docker full version

Install ubuntu docker full version

Troubled for a long time how to install the full version of ubuntu docker, and later found from the ssh log into docker mirror when prompted, you can use a single command to install the full version of ubuntu perfect.

command

unminimize

Implementation of the results

➜  ~ unminimize
This system has been minimized by removing packages and content that are
not required on a system that users do not log into.

This script restores content and packages that are found on a default
Ubuntu server system in order to make this system more suitable for
interactive use.

Reinstallation of packages may fail due to changes to the system
configuration, the presence of third-party packages, or for other
reasons.

This operation may take some time.

Would you like to continue? 

We're done!

Script content

Not every ubuntu version has found this script, so the script posted out.

Script is located /usr/local/sbin/unminimize.

Details are as follows:

#!/bin/sh

set -e

echo "This system has been minimized by removing packages and content that are"
echo "not required on a system that users do not log into."
echo ""
echo "This script restores content and packages that are found on a default"
echo "Ubuntu server system in order to make this system more suitable for"
echo "interactive use."
echo ""
echo "Reinstallation of packages may fail due to changes to the system"
echo "configuration, the presence of third-party packages, or for other"
echo "reasons."
echo ""
echo "This operation may take some time."
echo ""
read -p "Would you like to continue? [y/N]" REPLY
echo    # (optional) move to a new line
if [ "$REPLY" != "y" ] && [ "$REPLY" != "Y" ]

    exit 1

Production ubuntu mirror full version Docker

Once you know the above command, making Docker mirror is very easy.

Save the following fileDockerfile

FROM ubuntu:18.04
RUN export DEBIAN_FRONTEND=noninteractive && \
    bash -c 'yes | unminimize'

Operation is then performed to compile the image docker

docker build . -t ubuntu:18.04-full

You can easily perform a complete version of the mirror

docker run -it --rm ubuntu:18.04 bash

Compared

The method described in this blog relatively relatively cumbersome.
