I am trying to create a Haproxy in a Kubernetes cluster. So far so good, I manage to create the Docker Image and add the haproxy details. I am able to deploy it in kubernetes, but once deployed, all pods have 0/1 available because the haproxy service does not start.
Am I missing something here?
This is the docker image that I use:
FROM haproxy:1.7
RUN groupadd haproxy && useradd -g haproxy haproxy
COPY haproxy.cfg /etc/haproxy/haproxy.cfg
CMD touch /var/log/haproxy.log && chmod 777 /var/log/haproxy.log
CMD service rsyslog start && service haproxy start && aproxy -f /etc/haproxy/haproxy.cfgI am assuming you are using the haproxy published in dockerhub. You are overriding the CMD defined in the base image. CMD ["haproxy", "-f", "/usr/local/etc/haproxy/haproxy.cfg"]
You dont run "service" inside docker containers.
If you look at the base image all it does is run haproxy command. By default haproxy runs in the background and in order to make it run in foreground make sure you comment out the 'daemon' in your haproxy.cfg file.
