In this tutorial we will be using the following instructions: FROM You can read more about instructions and arguments in the dockerfile reference documentation Each line has an instruction and argument. The dockerfile format is fairly straightforward. Create a new directory for your docker build file.This will help keep everything organized and give you a place to store any extra files if needed. It is recommended that each docker file is contained in a separate directory.
We will go over how to create one for nginx on CentOS in this tutorial. A docker file is essentially a script which can recreate the building of your image. : PYCURL ERROR 22 - "The requested URL returned error: 404"Įrror: failure: repodata/2 from cr: No more mirrors to try.The recommended way to create images for sharing is from a docker file.
