Pre-requisite:

Tested Infrastructure

<table class="tg"> <tr> <th class="tg-yw4l">Platform</th> <th class="tg-yw4l">Number of Instance</th> <th class="tg-yw4l">Reading Time</th> </tr> <tr> <td class="tg-yw4l"> Play with Docker</td> <td class="tg-yw4l">1</td> <td class="tg-yw4l">5 min</td> </tr> </table>

Pre-requisite

Create an account with DockerHub
Open PWD Platform on your browser
Click on Add New Instance on the left side of the screen to bring up Alpine OS instance on the right side

Assignment:

Create an image with GIT installed
Tag your image as labs-git:v1.0
Create a container based on that image, and run git --version to check that it is installed correctly

Creating Dockerfile

FROM alpine:3.5
RUN apk update
RUN apk add git

Build Docker Image

docker build -t ajeetraina/alpine-git .

Tagging image as labs-git

docker tag ajeetraina/alpine-git ajeetraina/labs-git:v1.0

Verify the Images

$ docker images
REPOSITORY              TAG                 IMAGE ID            CREATED             SIZE
ajeetraina/alpine-git   latest              cb913e37a593        16 seconds ago      26.6MB
ajeetraina/labs-git     v1.0                cb913e37a593        16 seconds ago      26.6MB

Create a container

docker run -itd ajeetraina/labs-git:v1.0 /bin/sh

$ docker ps
CONTAINER ID        IMAGE                      COMMAND             CREATED             STATUS              PORTS               NAMES
