Unable to access localhost from pushgateway pod on openshift

[Nidhi Sharma]

Hi,

Do i need to make any config changes so that I can access localhost? Please help

When you are running an application inside a container "localhost" refers to the container, not the underlying host. You will need to use a different method to reference other pods, such as a service DNS name.

Thanks for replying Stuart. Even if I use service DNS, i can't access any API inside the pushgateway container. Below is the command. I get 404.

wget http://eaa-platform-pushgateway:9091/api/v1/status

As you are getting a 404 it sounds like you are hitting the container
correctly. Have you enabled the web API using --web.enable-admin-api?

Yes. I tried setting this flag but the pod goes in crashloopbackoff. Below are my docker file and entrypoint.sh. 

 Docker file :

FROM prom/pushgateway:v0.9.0

LABEL maintainer "MYCOM OSI"

# Allowed: debug, info, warn, error

ENV LOGLEVEL=warn

ADD /entrypoint.sh /bin/entrypoint.sh

USER root

RUN chmod +x /bin/entrypoint.sh

USER 65534

ENTRYPOINT [ "/bin/entrypoint.sh" ]

Entrypoint.sh

#!/bin/sh

exec "/bin/pushgateway --log.level=warn --web.enable-lifecycle --web.enable-admin-api"

Please tell me if there is anything wrong in the syntax.

Remove the double quotes.

What you've written is to try to run a command whose filename is exactly that one long string, including spaces.

I commited below script now but still pod is in crashloop

#!/bin/sh

exec /bin/pushgateway --web.enable-lifecycle --web.enable-admin-api

[Nidhi Sharma]

Below is the ideal script when pod is working fine. If I try to include any flag here, i get crashloop pod

#!/bin/sh

/bin/pushgateway --log.level=$LOGLEVEL

RESOLVED. after changing the version of pushgateway in dockerfile
