When clustercheck uses socat and IPv6, the healthcheck has to wrap the service IP in brackets for the call to succeed. Change-Id: I61da4f85ccf88f0287886334c8a9f43e3be8ef7e Closes-Bug: #1983266
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.
