Installing Ubuntu in Docker

Use the official Ubuntu image

There are many images associated with Ubuntu, where -s 10 parameters are used to search only those images that have been collected more than 10 times.

Note that the--stars parameter is not already supported in the Docker 1.12 release, so you can use the-F stars=n parameter.

Based on the results of the search, readers can choose to download the image and use it by themselves.

The following is an example of Ubuntu 14.04, which shows how to use this image to install some common software.

Start the -ti container with the parameters first, log in to bash, and view the release number of Ubuntu.

Basic Ubuntu Information

Ubuntu is a popular Linux distribution, and its own version of the software is often newer.

The warehouse is located in https://hub.docker.com/_/ubuntu/, which offers Ubuntu images from 12.04 to 16.10 versions of each.

How to use

The default is to start a minimized Ubuntu environment.

$ docker Run--name some-ubuntu-i-t Ubuntu[email protected]:/#

When trying to apt-get install a software directly, you will be prompted E: Unable to locate package .

1 [email protected]:/# apt-get Install Curl2Reading Package lists ... do3Building dependency tree4Reading state information ... do5 e:unable to locate package curl

This is not a command that is not supported by the system apt-get . The Docker image was created to simplify the removal of apt warehouse information, so you need to execute the apt-get update command to update the warehouse information first. After you update the information, you can successfully install the software via the Apt-get command.

First, install the Curl tool.

Next, install the Apache service.

Donethe following extra packages would be installed:  apache2-bin apache2-data libapr1 libaprutil1 libaprutil1-dbd-sqlite3  libaprutil1-ldap libxml2 sgml-base ssl-cert xml-core ...

Start the Apache service, and then use Curl to test local access.

 [email protected]:/# Service apache2 Start * Starting Web server Apache2 AH00558:apache2:Could not Reliabl Y determine the server ' s fully qualified domain name, using 172.17.0.2.

With -p the use of parameters to map the service port externally, you can allow the container external access to the service.
