Unable to run sensu check in a docker-compose context


I am dockerizing sensu infrastructure. Everything goes fine except the execution of checks.
I am using docker-compose according to this structure (docker-compose.yml):
sensu-core:
build: sensu-core/
links:
- redis
- rabbitmq
sensors-production:
build: sensors-production/
links:
- rabbitmq
uchiwa:
build: sensu-uchiwa
links:
- sensu-core
ports:
- "3000:3000"
rabbitmq:
build: rabbitmq/
redis:
image: redis
command: redis-server
My rabbitmq Dockerfile is pretty straightforward:
FROM ubuntu:latest
RUN apt-get -y install wget
RUN wget http://packages.erlang-solutions.com/erlang-solutions_1.0_all.deb
RUN dpkg -i erlang-solutions_1.0_all.deb
RUN wget http://www.rabbitmq.com/rabbitmq-signing-key-public.asc
RUN apt-key add rabbitmq-signing-key-public.asc
RUN echo "deb http://www.rabbitmq.com/debian/ testing main" | sudo tee /etc/apt/sources.list.d/rabbitmq.list
RUN apt-get update
RUN apt-get -y install erlang rabbitmq-server
CMD /etc/init.d/rabbitmq-server start && \
rabbitmqctl add_vhost /sensu && \
rabbitmqctl add_user sensu secret && \
rabbitmqctl set_permissions -p /sensu sensu ".*" ".*" ".*" && \
cd /var/log/rabbitmq/ && \
ls -1 * | xargs tail -f
So do the uchiwa Dockerfile:
FROM podbox/sensu
RUN apt-get -y install uchiwa
RUN echo ' \
{ \
"sensu": [ \
{ \
"name": "Sensu", \
"host": "sensu-core", \
"port": 4567, \
"timeout": 5 \
} \
], \
"uchiwa": { \
"host": "0.0.0.0", \
"port": 3000, \
"interval": 5 \
} \
}' > /etc/sensu/uchiwa.json
EXPOSE 3000
CMD /etc/init.d/uchiwa start && \
tail -f /var/log/uchiwa.log
Sensu core runs sensu-server & sensu-api. Here is his dockerfile:
FROM podbox/sensu
RUN apt-get -y install sensu
RUN echo '{ \
"rabbitmq": { \
"host": "rabbitmq", \
"vhost": "/sensu", \
"user": "sensu", \
"password": "secret" \
}, \
"redis": { \
"host": "redis", \
"port": 6379 \
}, \
"api": { \
"host": "localhost", \
"port": 4567 \
} \
}' >> /etc/sensu/config.json
CMD /etc/init.d/sensu-server start && \
/etc/init.d/sensu-api start && \
tail -f /var/log/sensu/sensu-server.log -f /var/log/sensu-api.log
sensors-production runs sensu-client along with a dumb metric, here is his Dockerfile:
FROM podbox/sensu
RUN apt-get -y install sensu
RUN echo '{ \
"rabbitmq": { \
"host": "rabbitmq", \
"vhost": "/sensu", \
"user": "sensu", \
"password": "secret" \
} \
}' >> /etc/sensu/config.json
RUN mkdir -p /etc/sensu/conf.d
RUN echo '{ \
"client": { \
"name": "wise_oracle", \
"address": "prod_sensors", \
"subscriptions": [ \
"web", "aws" \
] \
} \
' >> /etc/sensu/conf.d/client.json
RUN echo '{ \
"checks": { \
"dumb": { \
"command": "ls", \
"subscribers": [ \
"web" \
], \
"interval": 10 \
} \
} \
}' >> /etc/sensu/conf.d/dumb.json
CMD /etc/init.d/sensu-client start && \
tail -f /var/log/sensu/sensu-client.log
Running
docker-compose up -d
Everything goes OK. No errors in the logs, I can access the uchiwa dashboard, which shows me the defined client alright (keepalive requests seems to be OK). However, no check is available.
I noticed that no check request / check result is present in the log, as if the sensu server consider there is no check to run. Although, I have no idea why is that.
Could someone tell me what's going on more precisely? Thank you.
Check request/result will delivered via RabbitMQ, you can access to http://yourrabbitmqserver:15672 to see the queue and subscribed consumers.
Also make sure your server have some check.json files placed in /sensu/conf.d to schedule checks base on their interval
