ComponentPortAnnotationName annotation is used on the secrets that are created for each exposed port of the component.

DefaultS2ISrcBackupDir is the default path where odo backs up the component source.

DefaultS2ISrcOrBinPath is the default path where S2I expects source/binary artifacts in absence of $S2ISrcOrBinLabel in builder image Ref: https://github.com/openshift/source-to-image/blob/master/docs/builder_image.md#required-image-contents.

EnvS2IBuilderImageName is the label that provides the name of builder image in component.

EnvS2IDeploymentDir is an env var exposed to https://github.com/openshift/odo-init-image/blob/master/assemble-and-restart to indicate s2i deployment directory.

EnvS2IScriptsProtocol is an env var exposed to https://github.com/openshift/odo-init-image/blob/master/assemble-and-restart to indicate the way to access location of s2i scripts indicated by ${${EnvS2IScriptsURL}} above.

EnvS2IScriptsURL is an env var exposed to https://github.com/openshift/odo-init-image/blob/master/assemble-and-restart to indicate location of s2i scripts in this case assemble script.

EnvS2ISrcBackupDir is the env var that points to the directory that holds a backup of component source This is required bcoz, s2i assemble script moves(hence deletes contents) the contents of $ODO_S2I_SRC_BIN_PATH to $APP_ROOT during which $APP_DIR alo needs to be empty so that mv doesn't complain pushing to an already exisiting dir with same name.

EnvS2ISrcOrBinPath is an env var exposed by s2i to indicate where the builder image expects the component source or binary to reside.

EnvS2IWorkingDir is an env var to odo-init-image assemble-and-restart.sh to indicate to it the s2i working directory.

S2IDeploymentsDir is a set of possible S2I labels that provides S2I deployments directory This label is not uniform across different builder images.

CommonImageMeta has all the most common image data that is passed around within Odo.

CreateArgs is a container of attributes of component create action.

FakeClientset holds fake ClientSets this is returned by FakeNew to access methods of fake client sets.

S2IPaths is a struct that will hold path to S2I scripts and the protocol indicating access to them, component source/binary paths, artifacts deployments directory These are passed as env vars to component pod.

ServerInfo contains the fields that contain the server's information like address, OpenShift and Kubernetes versions.

UpdateComponentParams serves the purpose of holding the arguments to a component update request.
