Configuration

dib can be configured either by command-line flags, environment variables or configuration file.

The command-line flags have the highest priority, then environment variables, then config file. You can set some default values in the configuration file, and then override with environment variables of command-line flags.

Command-line flags

Example:

dib build --registry-url=gcr.io/project

Environment variables

dib auto-discovers configuration from environment variables prefixed with DIB_, followed by the capitalized, snake_cased flag name.

Example:

export DIB_REGISTRY_URL=gcr.io/project
dib build

Configuration file

dib uses a YAML configuration file in addition to command-line arguments. It will look for a file names .dib.yaml in the current working directory. You can change the file location by setting the --config (-c) flag.

The YAML keys are equivalent to the flag names, in snake_case.

Example:

# .dib.yaml
registryUrl: gcr.io/project
...
