I'm trying to set environment variables in docker container during the build but without success. setting them when using run command works but i need to set them during the build. dockerfile from. Split your dockerfile instructions into distinct stages to make sure that the resulting output only contains the files that are needed to run the application. using multiple stages can also let you build more efficiently by executing build steps in parallel. see multi stage builds for more information. Apply the following 21 dockerfile best practices to prevent security issues, optimize container security, and avoid common image errors and pitfalls. we have grouped our selected dockerfile best practices by topic. Use caching properly for your dockerfiles: docker containers are built very quickly as long as you make use of the caching capability. a quick set of gotchas and advices: add & volumes are cache invalidators. run commands are cached while unchanged.
