fehrenbacher/qrcode-server repository overview

⁠About

QR-Code Server is a dockerized Java (Amazon Corretto 17) rest application to generate qr codes based on ZXing Project. Find more informations, dockerfile and code at github.com:

https://github.com/tomcat128/qr-code-server⁠

⁠Running container

docker run --rm -p 8080:8080 -p 80:8080 --name qrcode-server fehrenbacher/qrcode-server:latest

If container is running, you can POST your requests to http://localhost:8080/⁠

RequestBody should look like: { "data": "https://www.github.com⁠", "errorLevel": "LOW", "imageSize": 200 }

⁠Add custom configuration

Lets say, we want to change the port of the application. Then create an folder with an "application.properties" inside it. Add for example "server.port=7777" to the configuration. Then run again the container with the following command:

docker run --rm -p 8080:7777 -p 80:7777 -v "$PWD":/srv/config --name qrcode-server qrcode-server:latest

With docker logs qrcode-server you can check the port the application was started.

But remember: 7777 is the port inside the container. You still only access the app with the mapped ports 80 and 8080.
