cannot deploy jenkins-external-services

When we try to do the step oc new-app --template=jenkins-external-services -p JENKINS_IP=XXX.XXX.XXX.XXX from http://blog.andyserver.com/2016/02/jenkins-slaves-openshift-external-jenkins-environment/ , we got this error;

    error: Endpoints "jenkins" is invalid: subsets[0].addresses[0].ip: Invalid value: "": must be a valid IPv4 address

I am getting the same problem on OSE 3.1.1.6 with a git pull as of a few mins ago.

[kurktchiev]

actually i fail with a bit more output:

--> Deploying template jenkins-external-services for "jenkins-external-services"
     With parameters:
      Jenkins Service Name=jenkins
      JENKINS_IP=xxx.xxx.xxx.xxx
--> Creating resources ...
    error: Endpoints "jenkins" is invalid: subsets[0].addresses[0].ip: invalid value '', Details: invalid IPv4 address
    service "jenkins" created
    error: Endpoints "jenkins-slave" is invalid: subsets[0].addresses[0].ip: invalid value '', Details: invalid IPv4 address
    service "jenkins-slave" created```

@xelfe @ebalsumgo ill investigate the issue and get back to you both

[sabre1041]

@xelfe @ebalsumgo Tested with OpenShift Enterprise 3.1.1

Here is what I observe when running the command

[root@master ~]# oc version
oc v3.1.1.6-16-g5327e56
kubernetes v1.1.0-origin-1107-g4c8e6f4
[root@master ~]# oc new-app --template=jenkins-external-services -p JENKINS_IP=10.1.4.2
--> Deploying template jenkins-external-services for "jenkins-external-services"
     With parameters:
      Jenkins Service Name=jenkins

--> Creating resources ...
    Endpoints "jenkins" created
    Service "jenkins" created
    Endpoints "jenkins-slave" created
    Service "jenkins-slave" created
--> Success
    Run 'oc status' to view your app.

Dunno:

root@osmaster0s:~:
----> oc version
oc v3.1.1.6-16-g5327e56
kubernetes v1.1.0-origin-1107-g4c8e6f4

I am getting the above message no matter what. I am setup on a 2 master, 3 node cluster. 3 nodes are label separated and house specific projects.

This is the code doing the validation

// IsValidIPv4 tests that the argument is a valid IPv4 address.
func IsValidIPv4(value string) bool {
    return net.ParseIP(value) != nil && net.ParseIP(value).To4() != nil
}

[kurktchiev]

I am guessing it might be a problem with the fact that in our installs docker initiates a slew of virtual interfaces maybe?

Also any dependency on root? At least in my environment RunAsAny is NOT set

[kurktchiev]

NM ignore above comment, I just ran through the dockerfiles and the templates and dont see anything that should get tripped up by that. Not sure where else to look to fix this.

[sabre1041]

@ebalsumgo would you be able to provide the IP address you are trying to use? if not, can you try to replicate my example from above and if it works, try to edit the service and substitute your address

[kurktchiev]

I am using an external IP (pointing it to our live/master Jenkins instance which lives outside of OSE) its in the 152.19.* range

[sabre1041]

@ebalsumgo I validated the IP address you provided against my own OpenShift 3.1 environment and used the latest Red Hat Container Development Kit

[kurktchiev]

@sabre1041 not really sure where that leaves us then :)

[techno-wizardry]

FYI I too am hit with this (tried with @sabre1041 IP example too) :

# oc version
oc v3.2.0.44
kubernetes v1.2.0-36-g4a3f9c5
# oc new-app --template=jenkins-external-services -p JENKINS_IP=10.1.4.2
--> Deploying template jenkins-external-services for "jenkins-external-services"
     With parameters:
      Jenkins Service Name=jenkins

    error: Endpoints "jenkins" is invalid: subsets[0].addresses[0].ip: Invalid value: "": must be a valid IPv4 address
    service "jenkins" created
    error: Endpoints "jenkins-slave" is invalid: subsets[0].addresses[0].ip: Invalid value: "": must be a valid IPv4 address
    service "jenkins-slave" created

[sabre1041]

@bigashman thanks for reporting the issue. Would you be able to share your system operating system as well.

Thanks

[techno-wizardry]

sure - I'm on:

# cat /etc/redhat-release
Red Hat Enterprise Linux Server release 7.2 (Maipo)
# uname -r
3.10.0-327.18.2.el7.x86_64

[sabre1041]

@xelfe @bigashman @ebalsumgo finally figured this one out

Strange it was not occurring on OSX. If you could give it a try again, it would be appreciated as to close this issue

[ghyde]

I was also having this issue on RHEL 7.2, but the recent commit fixed it.
