Con­tain­ers

This time (Feb 2023) I was need to in­stall and use Dock­er on Ma­cOS. Here are the steps pro­vid­ed by the de­fault Dock­er Desk­top Tu­to­r­i­al on Ma­cOS.

The Get­ting Start­ed project is a sim­ple GitHub repos­i­to­ry which con­tains every­thing you need to build an im­age and run it as a con­tain­er.

First, clone a repos­i­to­ry

Clone the repos­i­to­ry by run­ning Git in a con­tain­er.

docker run --name repo alpine/git \
clone https://github.com/docker/getting-started.git
docker cp repo:/git/getting-started/ .

You can al­so type the com­mand di­rect­ly in a com­mand line in­ter­face.

Now, build the im­age

A Dock­er im­age is a pri­vate file sys­tem just for your con­tain­er. It pro­vides all the files and code your con­tain­er needs.

cd getting-started
docker build -t docker101tutorial .

...
Use 'docker scan' to run Snyk tests against images to find vulnerabilities and learn how to fix them.

Run your first con­tain­er

Start a con­tain­er based on the im­age you built in the pre­vi­ous step. Run­ning a con­tain­er launch­es your ap­pli­ca­tion with pri­vate re­sources, se­cure­ly iso­lat­ed from the rest of your ma­chine.

docker run -d -p 80:80 --name docker-tutorial docker101tutorial
  • -d – run the con­tain­er in de­tached mode (in the back­ground)
  • -p 80:80 – map port 80 of the host to port 80 in the con­tain­er
  • dock­er/get­ting-start­ed – the im­age to use

Then vis­it http://localhost/, where a nice tu­to­r­i­al should be dis­played!

Now save and share your im­age

You must be signed in to Dock­er Hub to share your im­age. Sign in here.

Save and share your im­age on Dock­er Hub to en­able oth­er users to eas­i­ly down­load and run the im­age on any des­ti­na­tion ma­chine.

dockdocker tag docker101tutorial pa4080/docker101tutorial
docker push pa4080/docker101tutorial

Fi­nal­ly: See what you've saved on Hub.

Note: If you want to sign in from the Dock­er CLI, you’ll need a per­son­al ac­cess to­ken. An ac­cess to­ken is the on­ly pass­word ac­cept­ed by the CLI when you have 2FA en­abled.
