============
|
|
|
|
Promenade is using Hyperkube for all Kubernetes components: kubelet, kubectl, etc.
|
|
By default Hyperkube binary should be extracted from the image before running Promenade.
|
|
This is done by external scripts and is not integrated into Promenade source code.
|
|
The other way is to let Promenade do the job and extract binary. This one is more complicated,
|
|
needs to share Docker socket inside Promenade container and is optional.
|
|
|
|
Default behavior
|
|
----------------
|
|
|
|
IMAGE_HYPERKUBE should be exported and set to appropriate value.
|
|
Before running build-all CLI for Promenade need to run utility container which will copy binary from image to a shared location.
|
|
See tools/g2/stages/build-scripts.sh for reference.
|
|
|
|
|
|
Integrated solution
|
|
-------------------
|
|
|
|
To let Promenade extract binary need to provide more env vars and shared locations for Promenade container.
|
|
Also need to enable option --extract-hyperkube in Promenade CLI.
|
|
|
|
Define var for Docker socket(it should be available for user to read/write):
|
|
DOCKER_SOCK="/var/run/docker.sock"
|
|
|
|
Provide it for container:
|
|
-v "${DOCKER_SOCK}:${DOCKER_SOCK}"
|
|
-e "DOCKER_HOST=unix:/${DOCKER_SOCK}"
|
|
|
|
Provide additional var(it's for internal operations):
|
|
-e "PROMENADE_TMP_LOCAL=/${PROMENADE_TMP_LOCAL}"
