This commit irons out one of the pain points of the HCP rework by introducing a HCPPublisher interface, implemented both by the JSON Core, and the HCL2 PackerConfig, which keeps a map of the build names used by Packer to the build names pushed on HCP. This in turn lets us go back to the old implementation of the GetBuilds function, which returns a list of (filtered) builds, and eventually an error if something went wrong while processing.

Usage: packer validate [options] TEMPLATE
|
|
|
|
Checks the template is valid by parsing the template and also
|
|
checking the configuration with the various builders, provisioners, etc.
|
|
|
|
If it is not valid, the errors will be shown and the command will exit
|
|
with a non-zero exit status. If it is valid, it will exit with a zero
|
|
exit status.
|
|
|
|
Options:
|
|
|
|
-syntax-only Only check syntax. Do not verify config of the template.
|
|
-except=foo,bar,baz Validate all builds other than these.
|
|
-only=foo,bar,baz Validate only these builds.
|
|
-machine-readable Produce machine-readable output.
|
|
-var 'key=value' Variable for templates, can be used multiple times.
|
|
-var-file=path JSON or HCL2 file containing user variables, can be used multiple times.
|
|
-no-warn-undeclared-var Disable warnings for user variable files containing undeclared variables.
|
|
-evaluate-datasources Evaluate data sources during validation (HCL2 only, may incur costs); Defaults to false.
