Description

It is a correct example building arm docker image on x86 machine using travis CI.

• build is an excutable to build the docker image.
• start is an excutable to start a container of docker image.
• .travis.yml is a travis configuration file

Travis CI building process

On master branch, when the code on master branch is pushed, the building process will be triggered automatically, and the image will be delivered on docker hub dorrybamboo/rpi-x86-ex

Start a container on arm

On arm machine, eg, raspberry pi 3

docker run -d -p 8000:8000 dorrybamboo/rpi-x86-ex

Visit arm_machine_ip:8000 on the browser with html page displayed.

Explaination

Docker image delivery

In order to deliver the docker image built by travis CI, the travis CI has to know the username and password of docker hub account.

You can change your docker hub account by reconfiguring .travis.yml by following steps:

• Remove secure attributes on env.global in .travis.yml.
• Change the value of DOCKER_NAME and DOCKER_PASS in .env.
• ./set_docker_account.
