Ran into some problems. Networking seems to not work. #7

Environment: RHEL 7.3, docker installed from RHEL repo:

rpm -qa | grep docker
docker-rhel-push-plugin-1.10.3-55.el7.x86_64
docker-selinux-1.10.3-55.el7.x86_64
docker-1.10.3-55.el7.x86_64
docker-common-1.10.3-55.el7.x86_64

First problem: no docker-machine in this. So I downloaded/installed docker-machine.

The init.sh script somehow made it but I spot some messages that look wrong:

WARNING: Binding DNS on port 8053 instead of 53, which may be not be resolvable from all clients.
...
Host does not exist: "openshift"

I can login to OpenShift console but whatever template I try fails with:

error: couldn't get deployment database-1: Get https://172.30.0.1:443/api/v1/namespaces/localtest/replicationcontrollers/database-1: dial tcp 172.30.0.1:443: getsockopt: no route to host

Not sure how to go from here ...

eschabell commented 7 years ago

Can you update and provide log of your run of 'init.sh'? Is this on Fedora? CBS? That kind of info....

jwildeboer commented 7 years ago

I notice taht docker-machine ls doesn't show anything, docker ps does. I am guessing a mismatch between installed docker and docker-machine as the root cause of this weirdness.

RHEL 7.3, CSB, latest run of init.sh

I am aslo seeing a "Failed Sync" message in Events:

Error syncing pod, skipping: failed to "StartContainer" for "POD" with RunContainerError: "addNDotsOption: ResolvConfPath \"/var/lib/docker-latest/containers/dea8df91f3956f334aafec61ff08cc71cd5a201c8515b823727814351a132876/resolv.conf\" does not exist"

eschabell commented 7 years ago

I have not had mine generate IPs in the 10.* range, so maybe this is related to whatever network you are on?

Looks like you are having port issues.... would need to raise this with the OpenShift project as how they automate this setup is outside of this project.

Let me know if you need a name to contact?

jwildeboer commented 7 years ago

I will try again to run the init script at home. Could well be that the office network is interfering.
