juju deploy ch:opensearch on a substrate that doesn't set vm.max_map_count, vm.swappiness and net.ipv4.tcp_retries2
Let the unit(s) settle, and observe their eventual state
Expected behavior
Opensearch is up and running. If needed, the charm has configured sysctl and applied the required parameters.
Actual behavior
opensearch/3 blocked idle 2 <private IP> vm.max_map_count should be at least 262144 - vm.swappiness should be 0 - net.ipv4.tcp_retries2 should be 5
opensearch/4* blocked idle 3 <private IP> vm.max_map_count should be at least 262144 - vm.swappiness should be 0 - net.ipv4.tcp_retries2 should be 5
opensearch/5 blocked idle 4 <private IP> vm.max_map_count should be at least 262144 - vm.swappiness should be 0 - net.ipv4.tcp_retries2 should be 5
Versions
Operating system: Ubuntu 22.04.4 LTS
Juju CLI: 3.4.4-ubuntu-amd64
Juju agent: 3.4.4
Charm revision: 113 (2/edge)
LXD: N/A (openstack)
Log output
Juju debug log: Not provided due to the noise from the other units, the snippet below is more relevant.
I just saw that the documentation recommends to set these parameters at the model-config level with cloud-init.
This isn't really convenient, as the parameters will apply to all other units of the environment (frontends, ETL units, anything, ...)
Originally, cloud-init was mandatory to be set in order for OpenSearch to work. This PR updates the README and integration tests to remove this dependency, following recent charm changes.
Closes#359
