# `build` Command
|
|
|
|
The `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.
|
|
|
|
## Options
|
|
|
|
- `-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 `name` attribute 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=cleanup` (default), `-on-error=abort`, `-on-error=ask` - Selects
|
|
what to do when the build fails. `cleanup` cleans up after the previous
|
|
steps, deleting temporary files and virtual machines. `abort` exits without
|
|
any cleanup, which might require the next build to use `-force`. `ask`
|
|
presents 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 `name`
|
|
attribute is specified within the configuration. `-only` does 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.
