Extending single-master cluster to multi-master

[Daniel Kučera]

Hi,

the docs say that it's not possible to migrate from cluster with one master
to multiple masters.
Is it really so?
Why?
Can it be done manually?

Thanks.

Re: Node not getting taint

Node not getting taint

[Daniel Kučera]

Hi,

I'm trying to set taint on node:

$ oc adm taint nodes node-dev1 mode=testing:NoSchedule
node "node-dev1" tainted

However if I run describe, it shows no taints:

$ oc describe nodes/node-dev1
Name:node-dev1
Role:
Labels:beta.kubernetes.io/arch=amd64
beta.kubernetes.io/os=linux
kubernetes.io/hostname=node-dev1
Annotations:

Phase:

$ oc get nodes/node-dev1
NAME  STATUSAGE   VERSION
node-dev1   Ready 27m   v1.5.2+43a9be4

Bug again? How can I know if it's not set or only not displayed in describe?

OSEv3:vars ignore

[Daniel Kučera]

Hi all!

I'm running following command to add new node to cluster:

ansible-playbook -v -i /root/hosts-openshift-rhldev
openshift-ansible/playbooks/byo/openshift-master/scaleup.yml

If I add a variable to [OSEv3:vars] section, it's ignored. If I add
the variable on the host line, it is applied successfully.

To clarify - this doesn't work:

[OSEv3:vars]
openshift_master_identity_providers=[{'name': 'my_ldap_provider',
'challenge': 'true', 'login': 'true', 'kind':
'LDAPPasswordIdentityProvider', 'attributes': {'id': ['dn'], 'name':
['cn'], 'preferredUsername': ['uid']}, 'bindDN': '', 'bindPassword':
'', 'ca': '', 'insecure': 'true', 'url':
'ldap://1.2.3.4/cn=users,cn=accounts,dc=test,dc=local?uid?sub'}]

[new_nodes]
master2.test.local

and this does:

[OSEv3:vars]

[new_nodes]
master2.test.local openshift_master_identity_providers="[{'name':
'my_ldap_provider', 'challenge': 'true', 'login': 'true', 'kind':
'LDAPPasswordIdentityProvider', 'attributes': {'id': ['dn'], 'name':
['cn'], 'preferredUsername': ['uid']}, 'bindDN': '', 'bindPassword':
'', 'ca': '', 'insecure': 'true', 'url':
'ldap://1.2.3.4/cn=users,cn=accounts,dc=test,dc=local?uid?sub'}]"

What am I doing wrong? How can I have the settings in vars section
applied when running specific playbooks?

Thanks.

Deploy latest from web UI

[Daniel Kučera]

Hi,

I'm using S2I image builds into imagestream and I've disabled
"Automatically start new deployments when an image stream tag is
updated. " in DC of that image.

Now when I build new version - deployment doesn't change - this is OK.
But when I click "Deploy" in DC, it deploys old version of image.
I need to run "oc rollout latest dc/app -n app" to deploy latest
version of built image.

Is there some option in web UI to deploy latest image?

OpenShift Master:v1.5.0+031cbe4
Kubernetes Master:v1.5.2+43a9be4

Thanks.

Hi Tako.

You need to set incremental: true

Re: DevOps With OpenShift issues on Ubuntu 16.04

Hi Benjamin,

the image you are using probably expects httpd to run under root
account and this is not permitted by default (because it is a security
threat).
