This article is about building programs using docker containers. The editor thought it was very practical, so I shared it with you as a reference. Let's follow the editor and have a look.

Software architecture

Git clone https://github.com/pcdogyu/example-voting-app.git

Cd / home/centos/example-voting-app/vote

Docker build. -t voting-app

Docker images

Docker run-p 5000 purl 80 voting-app

Why didn't you respond? I'm sorry. I was wrong. Aws sg, add 5000 port rules.

There it is.

The log also shows the incoming data.

But clicking in made a mistake.

Check the log, redis.push post data failure Bird.

Redis error, let me start a redis

Docker run-d-name=redis redis

There is no local one.

Repeat the next one

Docker run-d-name=redis redis

Redis, get up.

Associate redis when you start app

Docker run-p 5000 80-- link redis:redis voting-app

The web page is normal.

Run a database

Docker run-d-name=db postgres:9.4

Downloading

Let's pack a worker and go to sleep.

Cd / home/centos/example-voting-app/worker

Docker build. -t worker-app

One night has passed. Postgres and voting app are packed.

Docker run-link redis:redis-link db:db worker-app

All four components are already running.

Build displays the app of the result

Cd / home/centos/example-voting-app/result

Docker build. -t result-app

Image under docker image

The result page is accessed using port 5001

Docker run-d-p 5001 80-- link db:db result-app

All five components are up.

Visit http://52.80.39.196:5001/

I was wrong. Add it to aws sg.

Refresh, we have a result.

The above is the specific operation of using the docker container to build the program, the steps are detailed and clear, if you encounter this problem in your daily work, I hope you can solve the problem through this article.
