@alexhung @danielmkn @MahithaB can we host this image on somewhere else?

I'm not capable of figuring out what firewall needs to be opened to pull this image.

I have all firewalls opened for releases-docker.jfrog.io but for this releases-pts-observability-fluentd.jfrog.io I can't figure out.

I have tcpdumped the network packages and found the following dns lookups:

releases-pts-observability-fluentd.jfrog.io  
releases.jfrog.io  
endpointdns-prod-use1-lb.jfrog.io  
k8s-jfrogsaa-jfrogsaa-fb6f041eda-44b5904933c69ac1.elb.us-east-1.amazonaws.com
jfrog-prod-use1-shared-virginia-main.s3.amazonaws.com  
s3-1-w.amazonaws.com  
s3-w.us-east-1.amazonaws.com
jfrog-prod-use1-shared-virginia-main.s3.amazonaws.com 
s3-1-w.amazonaws.com 

and I have requested a whitelist on all the above outbound on the firewall, but i still have image pull issues.

for now, i'm pulling/taging/pushing on my public dockerhub... this is very annoying
