Awx-task stuck on wait-for-migrations

fabeer · November 13, 2023, 9:17am

Hi,
On a RHEL8.8, I’ve installed AWX on single node K3s using AWX Operator using kurokobo procedure (GitHub - kurokobo/awx-on-k3s: An example implementation of AWX on single node K3s using AWX Operator, with easy-to-use simplified configuration with ownership of data and passwords.)


Client Version: v1.27.6+k3s1
Kustomize Version: v5.0.1
Server Version: v1.27.6+k3s1

$ kubectl get pod -n awx
NAME                                               READY   STATUS    RESTARTS        AGE

All seems Ok, but after few minute the web gui hangs and on the awx-task pod
On the awx-task pod I see the following errors:

kubectl logs -f awx-task-bdd85964b-njnsq  -n awx

If I run the awx-manage migrate --noinput, inside the awx-web pod, the following error is reported:

$ kubectl -n awx exec -it awx-web-85db9b66cb-9ncsd -c  awx-web -- bin/bash

After restarting the awx-task pod, everything starts working correctly again, only to have the same problem again after a few minutes

it looks like there’s a problem connecting to the postgres service
can you post your AWX resource to show us any customization that you have added

Are you using the Postgres that the operator deployed or are you using an externally managed Postgres.

fabeer · November 17, 2023, 2:10pm

I am using Postgres distributed by the operator

TheRealHaoLiu · November 17, 2023, 6:37pm

Is the Postgres pod healthy?

fabeer · November 20, 2023, 8:11am

It would seem so. Do you need the output of some other specific command?

Could you provide the output from following commands?

sudo systemctl status firewalld
sudo systemctl status nm-cloud-setup

kubectl -n kube-system get deployment,pod,svc -o wide
kubectl -n awx run -it --rm --restart=Never busybox --image=busybox:1.28 -- nsl
ookup awx-postgres-13
kubectl -n awx run -it --rm --restart=Never busybox --image=busybox:1.28 -- cat
 /etc/resolv.conf

kubectl -n awx exec -it deployment/awx-web -c awx-web -- bash -c 'PGPASSWORD=An
sible123! psql -h awx-postgres-13 -p 5432 -U awx awx -c "\l"'

Also try restarting CoreDNS:

kubectl -n kube-system delete pod -l k8s-app=kube-dns

Thanks, so is it possible that connect PSQL from awx-task container?

$ kubectl -n awx exec -it deployment/awx-task -c awx-task -- bash -c 'PGPASSWORD=<your password> psql -h awx-postgres-13 -p 5432 -U awx awx -c "\l"'

If awx-manage still shows Name or service not known error,

$ kubectl -n awx exec -it deployment/awx-task -c awx-task -- awx-manage showmigrations
$ kubectl -n awx exec -it deployment/awx-task -c awx-task -- awx-manage migrate

you should review the credentials.py.

$ kubectl -n awx exec -it deployment/awx-task -c awx-task -- cat /etc/tower/conf.d/credentials.py

kubectl -n awx exec -it deployment/awx-task -c awx-task -- bash -c 'PGPASSWORD=Ansible-Dais psql -h awx-postgres-13 -p 5432 -U awx awx -c "\l"'`
psql: error: could not translate host name "awx-postgres-13" to address: Name or service not known`

After restart pod:

kubectl delete  pod  $(kubectl get pod  -n awx | awk '{ print $1 }' |grep task) -n awx
pod "awx-task-79675b847b-8c8wr" deleted

I add as further useful information for analysis that the installation of k3s and awx was done on a server behind a proxy

kurokobo · November 27, 2023, 1:24pm

Hmm, wired

Is the resolv.conf of the awx-task container correct? (both right after startup and after the issue occurs)
- kubectl -n awx exec -it deployment/awx-task -c awx-task -- cat /etc/resolv.conf
Are there any oddities in the CoreDNS or K3s logs?
- sudo journalctl -u k3s --no-pager -n 100
- kubectl -n kube-system logs deployment/coredns --tail=100
Are there enough resources (CPU, memory, etc.) available?

It seems more like an internal K3s routing problem than an AWX problem. If you don’t mind losing all your data, I want to know uninstalling K3s and reinstalling latest v1.27.7+k3s2 k3s solves the issue or not.

A few days ago I installed version v1.28.3+k3s2, but the problem remained.
Do you still recommend testing with the version of k3s you indicated?

kurokobo · November 29, 2023, 12:49pm

Ah okay so it’s not required to try 1.27.7.

The fact that the same problem occurs in multiple K3s versions could be a VXLAN issue with Flannel or a resolv.conf issue with the K3s host.

Do you have any domains with wild card in your resolv.conf?
Can you reproduce the issue with CoreDNS logging enabled and see if the PSQL hostname is queried?

Add log under .:53 { by kubectl -n kube-system edit cm coredns
Restart CoreDNS: kubectl -n kube-system delete pod -l k8s-app=kube-dns
Watch the logs: kubectl -n kube-system logs -f deployment/coredns --tail=100
Try connectiong PSQL from awx-task container, and see how the hostname is queried when it success and fails: kubectl -n awx exec -it deployment/awx-task -c awx-task -- bash -c 'PGPASSWORD=<your password> psql -h awx-postgres-13 -p 5432 -U awx awx -c "\l"'

the resolv.conf is like this:

Thanks for the update. So, when the issue occurs, no queries are sent to CoreDNS? I believe this is preventing all name resolution within k3s, not just AWX.

Can you try wiping all rules for iptables and restarting k3s? Check to see if the issue resolves after restarting k3s and if the issue reappears a short time after it is resolved.

# Accept all traffic and wipe all rules
sudo iptables -P INPUT ACCEPT
sudo iptables -P FORWARD ACCEPT
sudo iptables -P OUTPUT ACCEPT
sudo iptables -t nat -F; sudo iptables -t mangle -F; sudo iptables -F; sudo iptables -X

# Restarting K3s re-creates all rules for K3s
sudo systemctl restart k3s

no changes, but…
… it seems to be a k3s related problem.

I create a simple Pod to use as a test environment for dns:

$ kubectl apply -f https://k8s.io/examples/admin/dns/dnsutils.yaml

$ kubectl get pods -o wide
NAME       READY   STATUS    RESTARTS   AGE     IP           NODE                           NOMINATED NODE   READINESS GATES
dnsutils   1/1     Running   0          3m40s   10.42.0.81   xxxx.yyyy.zzzz.   <none>           <none>

$ kubectl exec -i -t dnsutils -- nslookup kubernetes.default
Server:         10.43.0.10
Address:        10.43.0.10#53

Name:   kubernetes.default.svc.cluster.local
Address: 10.43.0.1

$ kubectl exec -ti dnsutils -- nslookup google.com
Server:         10.43.0.10
Address:        10.43.0.10#53

Non-authoritative answer:
Name:   google.com
Address: 142.250.180.142

But after about ten minutes the requests to the DNS began to give problems:

$ kubectl exec -i -t dnsutils -- nslookup kubernetes.default
;; connection timed out; no servers could be reached

command terminated with exit code 1

However, the pods were reachable via ip address

$ kubectl get pods -o wide -n kube-system

Problem disappeared for a while after restarting kube-dns…

So same behavior as awx.
I focus on the k3s side analysis
