Welcome to docker’s documentation!

Here I have made a documentation for docker image/container for esajpip server under Summer of Code in Space program 2019

Check my container at https://hub.docker.com/r/dhiraj240/dockeresa

Points to ponder while developing docker image:

1. To reduce container size use

   FROM alpine Inside Dockerfile

2. To optimize the Dockerfile structure use the process of building a script first like below

   Inside script.sh use

   #! /bin/sh <follow up the script development>

• You can check my script.sh at https://github.com/Dhiraj240/dockeresa/blob/master/script.sh

• Don’t forget to make the script executable using

  chmod +x script.sh

3. Then use below boilerplate in Dockerfile

   COPY script.sh /script.sh CMD  ["/script.sh"]

• Then do below thing inside your Dockerfile directory

  docker build .

4. There may be the case you face Docker Daemon error while executing docker build .

• Don’t worrry use below command

  sudo chmod 666 /var/run/docker.sock

5. Put your container on Docker Hub for that use below process

   • First signup on Docker Hub and create repository name.

   • Use docker login

   • Then use docker images

     It will list the docker image name and image id which you need to copy.

   • Now use docker tag <image id> <username>/<reponame>:<tag>

     Here tag could be like 01, 1.0 etc.

   • Finally do docker push <username>/<reponame>
