Description:
Hi,

I had no issue to add HTTP access to binami elasticsearch on GCP for previous projects, but I’m unable to succeed on my new one.

The steps I followed:

  1. Create a Bitnami elasticsearch VM. Everything seems to be ok, I checked that with sudo /opt/bitnami/ctlscript.sh status and sudo vi /opt/bitnami/var/log/first-boot.log
  2. Create a static external IP linked to the VM on GCP
  3. Update the /opt/bitnami/elasticsearch/config/elasticsearch.yml configuration: network.host is 0.0.0.0 and network.public_host is my static external IP (34.76.167.21).
  4. I restarted the ES instance just to be sure with sudo /opt/bitnami/ctlscript.sh restart
  5. On ES reboot, my external IP is displayed so everything seems fine

Then I added firewall rule on GCP following your guide. I tried everything:

  • create a rule where all ports all methods are allowed
  • create a rule where only ports 80 and 9200 with tcp are allowed
  • specify Target tags with the VM tag, allow all instances
  • directly modify the VM and check Allow HTTP trafic and Allow HTTPS trafic

None of that is working, even if I correctly see the rules applied on my instance when I click on Network interface > default > Firewall rules.

I get a Error: connect ECONNREFUSED when I try to access the instance.

Hello @NicolasV,

I can see your port is open. You can use this command:

nc -zv -w3  XXX.XXX.XXX.XXX 9200
XX.XX.XX.XX.bc.googleusercontent.com [XXX.XXX.XXX.XXX] 9200 (?) open

I could also access the API via browser. However, port 80 is not open

I hope it helps
