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.

# `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` - Builds all the builds except those with the given
|
||
|
|
comma-separated names. Build names by default are the names of their builders,
|
||
|
|
unless a specific `name` attribute is specified within the configuration.
|
||
|
|
|
||
|
|
- `-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 build the builds with the given comma-separated
|
||
|
|
names. Build names by default are the names of their builders, unless a
|
||
|
|
specific `name` attribute is specified within the configuration.
|
||
|
|
|
||
|
|
- `-parallel=false` - Disable parallelization of multiple builders (on by
|
||
|
|
default).
