--push Pushes the built container image to the registry.
|
|
|
|
${_BOLD}You can use the following ENV variables to customize the build:${_CLEAR}
|
|
|
|

|
|
${_GREEN}Default:${_CLEAR} netbox-community
|
|
|
|
SRC_REPO The name of the repository to use (i.e. github.com/\${SRC_ORG}/\${SRC_REPO}).

|
NETBOX_PATH The path where netbox will be checkout out.
|
|
Must not be outside of the netbox-docker repository (because of Docker)!
|
|
${_GREEN}Default:${_CLEAR} .netbox
|
|
|
|
SKIP_GIT If defined, git is not invoked and \${NETBOX_PATH} will not be altered.
|
|
This may be useful, if you are manually managing the NETBOX_PATH.
|
|
${_GREEN}Default:${_CLEAR} undefined
|
|
|
|
TAG The version part of the image tag.
|
|
${_GREEN}Default:${_CLEAR}
|
|
When <branch>=master: latest
|
|
When <branch>=develop: snapshot
|
|
Else: same as <branch>
|
|
|
|
IMAGE_NAMES The names used for the image including the registry
|
|
Used for tagging the image.
|
|
${_GREEN}Default:${_CLEAR} docker.io/netboxcommunity/netbox
|
|
${_CYAN}Example:${_CLEAR} 'docker.io/netboxcommunity/netbox quay.io/netboxcommunity/netbox'
|
|
|
|
DOCKER_TAG The name of the tag which is applied to the image.
|
|
Useful for pushing into another registry than hub.docker.com.
|
|
${_GREEN}Default:${_CLEAR} \${DOCKER_REGISTRY}/\${DOCKER_ORG}/\${DOCKER_REPO}:\${TAG}
|
|
|
|
DOCKER_SHORT_TAG The name of the short tag which is applied to the
|
|
image. This is used to tag all patch releases to their
|
|

|
|
|
DOCKER_FROM The base image to use.
|
|
${_GREEN}Default:${_CLEAR} 'ubuntu:23.10'
|
|
|
|
BUILDX_PLATFORMS

${_CYAN}Example:${_CLEAR} 'linux/amd64,linux/arm64'
|
|
${_GREEN}Default:${_CLEAR} 'linux/amd64'
|
|
|
|
BUILDX_BUILDER_NAME
|
|
If defined, the image build will be assigned to the given builder.
|
|
If you specify this variable, make sure that the builder exists.
|
|
If this value is not defined, a new builx builder with the directory name of the

|
current directory (i.e. '$(basename "${PWD}")') is created."
|
|
${_CYAN}Example:${_CLEAR} 'clever_lovelace'
|
|
${_GREEN}Default:${_CLEAR} undefined
|
|
|
|
BUILDX_REMOVE_BUILDER
|
|
If defined (and only if BUILDX_BUILDER_NAME is undefined),
|
|
then the buildx builder created by this script will be removed after use.
|
|
This is useful if you build NetBox Docker on an automated system that does
|
|
not manage the builders for you.
|
|
${_CYAN}Example:${_CLEAR} 'on'
|
|
${_GREEN}Default:${_CLEAR} undefined
