Because healthchecks are provided via packaging in the build process, you cannot update the image yaml files and make healthcheck changes in a single commit. They need a level of coordination to not break things. Change-Id: Id2d6690d883def2c067af14b03a4502e259d3c2f

Health check commands
The scripts in this directory are meant to implement the container-healthcheck blueprint. They are written to be compatible with the Docker HEALTHCHECK api.
The scripts expect to source
/usr/share/tripleo-common/healthcheck/common.sh
. If you
want to run scripts without installing to that file, you can set the
HEALTHCHECKS_DIR
environment variable, e.g:
$ export HEALTHCHECKS_DIR=$PWD
$ ./heat-api
{"versions": [{"status": "CURRENT", "id": "v1.0", "links": [{"href": "http://192.168.24.1:8004/v1/", "rel": "self"}]}]}

Notes about changing healthchecks
Because healthchecks are provided via a package when building containers, you cannot rename or remove a health check in combination with a change to a, file in tripleo-common/container-images/. Changes need to be backwards and forwards compatible when updating healthchecks. You may also need to land a new healthcheck first and update the container build process in a subsequent change that lands later.
