### Building multiple container images

The step allows you to build multiple container images with one run.
This is suitable in case you need to create multiple images for one microservice, e.g. for testing.

All images will get the same "root" name and the same versioning.<br />
**Thus, this is not suitable to be used for a monorepo approach!** For monorepos you need to use a build tool natively capable to take care for monorepos
or implement a custom logic and for example execute this ` + "`" + `kanikoExecute` + "`" + ` step multiple times in your custom pipeline.

You can activate multiple builds using the parameter [containerMultiImageBuild](#containermultiimagebuild)

Behavior can be adapted using:

* [containerMultiImageBuildExcludes](#containermultiimagebuildexcludes) for defining excludes
* [containerMultiImageBuildTrimDir](#containermultiimagebuildtrimdir) for removing parent directory part from image name

Examples:

#### Multiple containers in sub directories

Configuration as follows:

` + "`" + `` + "`" + `` + "`" + `
general:
  containerImageName: myImage
steps:
  kanikoExecute:
    containerMultiImageBuild: true
` + "`" + `` + "`" + `` + "`" + `

Following Dockerfiles are available in the repository:

* sub1/Dockerfile
* sub2/Dockerfile

Following final image names will be built:

* ` + "`" + `myImage-sub1` + "`" + `
* ` + "`" + `myImage-sub2` + "`" + `

#### Multiple containers in sub directories while trimming a directory part

Configuration as follows:

` + "`" + `` + "`" + `` + "`" + `
general:
  containerImageName: myImage
steps:
  kanikoExecute:
    containerMultiImageBuild: true
    containerMultiImageBuildTrimDir: .ci
` + "`" + `` + "`" + `` + "`" + `

Following Dockerfiles are available in the repository:

* .ci/sub1/Dockerfile
* .ci/sub2/Dockerfile

Following final image names will be built:

* ` + "`" + `myImage-sub1` + "`" + `
* ` + "`" + `myImage-sub2` + "`" + ``,
