Configuration playbooks for StackTach.v3 deployments
Assumes an inventory value that has nodes or groups that start with "stv3-api" or "stv3-workers".
Execution would look like:
Assumes a stv3-db setup already exists.
There are also roles for database and api. The
common role is responsible for installing the tarball and creating the necessary user/group accounts. Both the API and workers depend on the common role since they both require the codebase and winchester configuration files.
What it does
/etc/stv3directory for configuration data
/var/run/stv3directory for pid files
/var/log/stv3directory for log files
- Copies config files to
- Copies init.d files to
/etc/init.dfor yagi-events and pipeline-worker
- Copies and expands the StackTach.v3 tarball to
- Starts the yagi worker daemon and the winchester worker (yagi-events and pipeline-worker respectively)
The init.d files handle the .pid file creation and running as stv3 user.
While yagi-events and pipeline-worker are capable to running daemonized, we don't use that code. Instead, we let the init.d scripts handle the backgrounding and process management.
The connection from the host machine to the target machine has to have a secure account already created for anisble to run. Currently it assumes an account called
stacktach and it has root capabilities. When the daemons run, they run as
stv3 ... which is just a service account.
