packer build command takes a template and runs all the builds within it
in order to generate a set of artifacts. The various builds specified within a
template are executed in parallel, unless otherwise specified. And the
artifacts that are created will be outputted at the end of the build.
-color=false- Disables colorized output. Enabled by default.
-debug- Disables parallelization and enables debug mode. Debug mode flags the builders that they should output debugging information. The exact behavior of debug mode is left to the builder. In general, builders usually will stop between each step, waiting for keyboard input before continuing. This will allow the user to inspect state and so on.
-except=foo,bar,baz- Run all the builds and post-processors except those with the given comma-separated names. Build and post-processor names by default are their type, unless a specific
nameattribute is specified within the configuration. Any post-processor following a skipped post-processor will not run. Because post-processors can be nested in arrays a different post-processor chain can still run. A post-processor with an empty name will be ignored.
-force- Forces a builder to run when artifacts from a previous build prevent a build from running. The exact behavior of a forced build is left to the builder. In general, a builder supporting the forced build will remove the artifacts from the previous build. This will allow the user to repeat a build without having to manually clean these artifacts beforehand.
-on-error=ask- Selects what to do when the build fails.
cleanupcleans up after the previous steps, deleting temporary files and virtual machines.
abortexits without any cleanup, which might require the next build to use
askpresents a prompt and waits for you to decide to clean up, abort, or retry the failed step.
-only=foo,bar,baz- Only run the builds with the given comma-separated names. Build names by default are their type, unless a specific
nameattribute is specified within the configuration.
-onlydoes not apply to post-processors.
-parallel-builds=N- Limit the number of builds to run in parallel, 0 means no limit (defaults to 0).
-timestamp-ui- Enable prefixing of each ui output with an RFC3339 timestamp.
-var- Set a variable in your packer template. This option can be used multiple times. This is useful for setting version numbers for your build.
-var-file- Set template variables from a file.
