There may be many issues with doing something like this. Two come to mind immediately. The security group the EC2 node is in must be configured to allow the necessary traffic in and out of the node. The default node IP address for the EC2 node is its internal IP address. The DO nodes won’t be able to use this. The EC2 node would need to be configured to use its external IP address.

SG allows traffic from anywhere for both inbound and outbound.

Are there any errors when the pod crashes?

The pod crashes because it’s not able to connect to mongodb atlas But I also noticed a lot of rancher agent containers been created on that server, last count was over 30

Interesting. Sounds like a networking issue to me, but I’m not privy to your setup. A wise person once told me, “If you don’t think it’s the security groups, check the security groups.”

I’ll recheck the SG. Thank you @agreeable-waiter-30020

It should be possible with a little configuration magic.

Thank you, I’ll keep on troubleshooting
