Generate app image from source code
Pack Build uses Cloud Native Buildpacks to create a runnable app image from source code.
Pack Build requires an image name, which will be generated from the source code. Build defaults to the current directory, but you can use --path to specify another source code directory. Build requires a builder, which can either be provided directly to build using --builder, or can be set using the set-default-builder command. For more on how to use pack build, see: https://buildpacks.io/docs/app-developer-guide/build-an-app/.
pack build <image-name> [flags]
pack build test_img --path apps/test-app --builder cnbs/sample-builder:bionic
-B, --builder string Builder image (default "cnbs/sample-builder:bionic")
-b, --buildpack strings Buildpack to use. One of:
a buildpack by id and version in the form of '<buildpack>@<version>',
path to a buildpack directory (not supported on Windows),
path/URL to a buildpack .tar or .tgz file, or
a packaged buildpack image name in the form of '<hostname>/<repo>[:<tag>]'
Repeat for each buildpack in order, or supply once by comma-separated list
-r, --buildpack-registry string Buildpack Registry by name
--cache-image string Cache build layers in remote registry. Requires --publish
--clear-cache Clear image's associated cache before building
-D, --default-process string Set the default process type. (default "web")
-d, --descriptor string Path to the project descriptor file
--docker-host string Address to docker daemon that will be exposed to the build container.
If not set (or set to empty string) the standard socket location will be used.
Special value 'inherit' may be used in which case DOCKER_HOST environment variable will be used.
This option may set DOCKER_HOST environment variable for the build container if needed.
-e, --env stringArray Build-time environment variable, in the form 'VAR=VALUE' or 'VAR'.
When using latter value-less form, value will be taken from current
environment at the time this command is executed.
This flag may be specified multiple times and will override
individual values defined by --env-file.
Repeat for each env in order, or supply once by comma-separated list
NOTE: These are NOT available at image runtime.
--env-file stringArray Build-time environment variables file
One variable per line, of the form 'VAR=VALUE' or 'VAR'
When using latter value-less form, value will be taken from current
environment at the time this command is executed
NOTE: These are NOT available at image runtime."
--gid int Override GID of user's group in the stack's build and run images. The provided value must be a positive number
-h, --help Help for 'build'
--lifecycle-image string Custom lifecycle image to use for analysis, restore, and export when builder is untrusted.
--network string Connect detect and build containers to network
-p, --path string Path to app dir or zip-formatted file (defaults to current working directory)
--publish Publish to registry
--pull-policy string Pull policy to use. Accepted values are always, never, and if-not-present. (default "always")
--run-image string Run image (defaults to default stack's run image)
-t, --tag strings Additional tags to push the output image to.
Repeat for each tag in order, or supply once by comma-separated list
--trust-builder Trust the provided builder
All lifecycle phases will be run in a single container (if supported by the lifecycle).
--volume stringArray Mount host volume into the build container, in the form '<host path>:<target path>[:<options>]'.
- 'host path': Name of the volume or absolute directory path to mount.
- 'target path': The path where the file or directory is available in the container.
- 'options' (default "ro"): An optional comma separated list of mount options.
- "ro", volume contents are read-only.
- "rw", volume contents are readable and writeable.
- "volume-opt=<key>=<value>", can be specified more than once, takes a key-value pair consisting of the option name and its value.
Repeat for each volume in order, or supply once by comma-separated list
--workspace string Location at which to mount the app dir in the build image
--no-color Disable color output
-q, --quiet Show less output
--timestamps Enable timestamps in output
-v, --verbose Show more output
