This git repo provides Sensu in a Docker container.
Project: [https://github.com/sstarcher/docker-sensu] (https://github.com/sstarcher/docker-sensu)
Docker image: [https://registry.hub.docker.com/u/sstarcher/sensu/] (https://registry.hub.docker.com/u/sstarcher/sensu/)
This is a base container for Sensu Core. It contains sensu-api
, sensu-client
, sensu-server
, but does not contain any plugins.
Default configuration allows for local linkage to rabbitmq
and redis
, by using docker links. If you need to reference external servers set the following variables as needed.
This container can be configured to use runtime system information for checks and metrics from it's host.
Installed plugins for now can change without warning. If you need a specific plugin installed either build a container based off of this one our use RUNTIME_INSTALL
to ensure your plugins are installed.
The client by default only loads files from /etc/sensu/conf.d
.
The API by default loads files from:
/etc/sensu/conf.d
/etc/sensu/check.d
The server by default loads files from:
/etc/sensu/conf.d
/etc/sensu/check.d
/etc/sensu/handlers
These defaults could be configured via environment variables:
ENV CONFIG_DIR /etc/sensu/conf.d
ENV CHECK_DIR /etc/sensu/check.d
ENV HANDLERS_DIR /etc/sensu/handlers
If you want sensu-client
to use runtime system information for checks and metrics from container's host system (not from sensu
container itself) you should:
- Define volumes to access host's filesystem from
sensu
container :
/dev:/host_dev/:ro
/proc:/host_proc/:ro
/sys:/host_sys/:ro
- Redefine environment variables :
HOST_DEV_DIR: /host_dev
HOST_PROC_DIR: /host_proc
HOST_SYS_DIR: /host_sys
All Sensu plugins will be automatically configured to use these paths instead of default ones.
