[caasp-beta] CaaS 1.0 beta2 pods issues with behind proxy server

[Ns, Rushi]

Hi Robert,

Thanks I have done those already but nothing working except you mentioned “cluster.local” which is missing. I will try this and let you know.

As you mentioned you should  try to provide that  information  during the installation  or some sort of post-steps as all most all enterprise customers have proxy to go internet.

You should try  similar to what  Redhat openshift container platform installation way they have a step where they ask the below proxy details during simple or advanced installation method.
FYI,  I have few clusters with  openshift_container_platform and It works , whereas CAASP I am having issues ? ii have informed this to one of your engineer (Alejandro Bonilla) directly before asking the list community) . Anyways I will try adding the missing parameter and let you know my results.

 

 ==============Redhat Openshift Container Platform Installation step====================
If a proxy is needed to reach HTTP and HTTPS traffic please enter the name below.

This proxy will be configured by default for all processes needing to reach systems outside

the cluster.

More advanced configuration is possible if using ansible directly:
https://docs.openshift.com/enterprise/latest/install_config/http_proxies.html
Specify your http proxy ? (ENTER for none) []: http://proxy.pal.sap.corp:8080

Specify your https proxy ? (ENTER for none) [http://proxy.pal.sap.corp:8080]:

All hosts in your openshift inventory will automatically be added to the NO_PROXY value.

Please provide any additional hosts to be added to NO_PROXY. (ENTER for none)

[]:

Rushi.

    Hi there,
    
    Kubernetes pods can run behind a proxy, but this currently requires you 
    to edit /etc/sysconfig/docker on each node, and add an entry for your proxy:
    
    HTTP_PROXY=http://proxy:8080
    HTTPS_PROXY=http://proxy:8080
    
    Replace the proxy URL accordingly. After this edit, restart the docker 
    daemon with:
    
    sudo systemctl restart docker.service
    
    This will address the Docker daemon's ability to pull containers.
    
    As far as proxied Internet access within the containers themselves, you 
    will need to add environment variables to the Kubernetes pod descriptors 
    that add the HTTP_PROXY and HTTPS_PROXY and NO_PROXY variables accordingly.
    
    Using the Kubernetes guestbook example, you would add the following to 
    the env section here: 
    https://github.com/kubernetes/kubernetes/blob/master/examples/guestbook/frontend-deployment.yaml#L33
    
    - name: HTTP_PROXY
       value: http://proxy:8080
    - name: HTTPS_PROXY
       value: http://proxy:8080
    - name: NO_PROXY
       value: 127.0.0.1,localhost,cluster.local
    
    In this example, the NO_PROXY is very important, along with the 
    cluster.local entry so that services running within your container 
    network are not proxied (using kube-dns for service discovery).
    
    We should improve this situation via configuration (but I can't commit 
    to it!) as this will be a common scenario for enterprise customers.
    
    Hope this helps,
    
    Robert
