Creating a Docker image and upload it to Docker Hub

Creating the Docker image
I'm going to use a Docker image to be able to use multiple github accounts from the same machine without so much trouble. To keep the image small I will use Alpine as a base image and only install the basics: git, vim, openssh-client.
In order to build the image we need to create a new file called Dockerfile and write the following:
FROM alpine:latest LABEL maintainer="@ech0Server" RUN apk update RUN apk add git vim openssh-client
Then, to build the docker image run:
docker build -t username/imagename:latest .
This command not only will build the image but it will tag it with the -t option, for my case I did:
docker build -t drverboten/multigitaccount:latest .
I will assume that you already have a Docker Hub account or create a docker hub account, then:
$ export DOCKER_ID_USER="username" $ docker login #it will prompt you for your username and password
If you followed the previous instructions your image should be already tagged, if not then you can tag your image by:
docker tag my_image $DOCKER_ID_USER/my_image
Finally we can push the Docker image to the Hub:
docker push drverboten/multigitaccount:latest
After that is completed you can go to: https://hub.docker.com/u/username and see that the image was successfully uploaded.
My image can be found here: https://hub.docker.com/r/drverboten/multigitaccount/
And you can pull it by doing:
docker pull drverboten/multigitaccount
Following folks on dev.to has always been key to customizing the kind of content you're more likely to see in your feed and notifications, but now that we have DEV Connect I feel like there is even more we can do by following folks with shared interests and willingness to be helpful.
