To build the github-secrets-generator container (requires podman or docker):

Usage: $0 --build
Example: $0 --build

To check if a secret already exists in a repo:

Usage: $0 -r [GH org/project] [SECRET_TO_CHECK]
Example: $0 -r eclipse-che/che-theia CHE_BOT_GITHUB_TOKEN
Example: $0 -r che-incubator/jetbrains-editor-images CHE_INCUBATOR_BOT_GITHUB_TOKEN

To list existing secrets by name:

Usage: $0 -r [GH org/project] --list
Example: $0 -r eclipse-che/che-theia --list

To upload 1 or more secrets from a file (one per line):

Usage: $0 -r [GH org/project] -f [SECRET_FILE]
Example: $0 -r eclipse-che/che-dashboard -f mykeys.txt

Plaintext secret file format: one entry per line, key-value separated by a space

KEY1_NAME VALUE1
KEY2_NAME VALUE2
