simple ClickHouse instance with PVC Installation is failing while starting pod #1464
Comments

Let's check, is /var/lib/clickhouse present in pod mounts ? |
|
It is there |
|
Which component responsible for second container with sleep 30 and securityContext? I think the root reason is securityContext:
allowPrivilegeEscalation: false
capabilities:
drop:
- ALL
runAsNonRoot: true
runAsUser: 1000730000to strict security context could we change it to following according to internal docker image uid? securityContext:
runAsUser: 101
runAsGroup: 101
fsGroup: 101
allowPrivilegeEscalation: false
capabilities:
drop: [ "ALL" ]
add: [ "CAP_NICE", "CAP_IPC_LOCK" ]If we can't change securityContext could we add env:
- name: CLIKCHOUSE_UID
value: 1000730000 to Something like that should work spec:
defaults:
templates:
podTemlate: custom-uid
templates:
podTemplates:
- name: custom-uid
spec:
containers:
- name: clickhouse
image: clickhouse/clickhouse-server:latest
env:
- name: CLIKCHOUSE_UID
value: 1000730000
- name: CLIKCHOUSE_GID
value: 1000730000 |

Tried below snippet but adding below snippet resulted in pending instance creation even after 3 mins it remains in pending state
while without the above snippet , it got created in few sec.
|
|
which
|
|
|
apply changes from #1464 (comment) and when status will share
|
|
No success. Even after 65m , no update . One thing i notice that "podTemlate: custom-uid" is not missing in respective section. |
|
check clickhouse-operator logs
check
and |
|
also check |
|
In operator log , got the issue which is fixed by adding quotes in env values. But again same issue while starting the pod |
|
need to figure out, which component added security context in your OpenShift? |
|
I think default "PodSecurityPolicy" is enabled. I don't have any other security / policy enforcer tool installed. |
|
|
let's apply CLICKHOUSE_DO_NOT_CHOWN=1 spec:
defaults:
templates:
podTemlate: custom-uid
templates:
podTemplates:
- name: custom-uid
spec:
containers:
- name: clickhouse
image: clickhouse/clickhouse-server:latest
env:
- name: CLIKCHOUSE_UID
value: "1000730000"
- name: CLIKCHOUSE_GID
value: "1000730000"
- name: CLICKHOUSE_DO_NOT_CHOWN
value: "1" |

same issue |

@Rajpratik71 , is it resolved? What is a reason of CrashLoopBackOff? (you should be able to see it in container logs) Do you need clickhouse-logs container, btw? It is rarely useful |
@alex-zaitsev same issue. getting below in log |
|
@Rajpratik71 , have you tried adding security context as suggested above? Could you post here full CHI spec deleting sensitive data? |
