The axis directives inside an exclude generate a set of combinations (similar to generating the matrix cells). In the top-level pipeline block and each stage block. Providing flow control, therefore, rests on Groovy expressions, such as the Hi. This secret should contain the contents of ~/.aws/credentials. This option is valid for docker and dockerfile.
