# [NAME](#NAME)

caddy-adapt - Adapts a configuration to Caddy's native JSON

# [SYNOPSIS](#SYNOPSIS)

**caddy adapt --config \[--adapter ] \[--pretty] \[--validate] \[--envfile ] \[flags]**

# [DESCRIPTION](#DESCRIPTION)

Adapts a configuration to Caddy's native JSON format and writes the output to stdout, along with any warnings to stderr.

If --pretty is specified, the output will be formatted with indentation for human readability.

If --validate is used, the adapted config will be checked for validity. If the config is invalid, an error will be printed to stderr and a non- zero exit status will be returned.

If --envfile is specified, an environment file with environment variables in the KEY=VALUE format will be loaded into the Caddy process.

If you wish to use stdin instead of a regular file, use - as the path.
