RELATED IDEAS

change the value of Nginx configuration "server_names_hash_bucket_size" to larger than 128

the value of nginx configuration "server_names_hash_bucket_size" is fixed with 128, which will cause the gateway pod failed to start when the length of baseDomain is larger than 128 with following error.


# kubectl logs gateway-67965f476b-l8f45 -n instana-core

nginx: [emerg] could not build server_names_hash, you should increase server_names_hash_bucket_size: 128


it's better to set the value to 255 due to the RFC specification ( https://www.freesoft.org/CIE/RFC/1035/9.htm).

    Hi Jun Tan,

    this was delivered as part of 223-2. Could you confirm by adding this to your CoreSpec?

    coreSpec:
    componentConfigs:
    - name: gateway
    properties:
    - name: nginx.http.server_names_hash_bucket_size
    value: "128"


    Replace 128 with 255 or any value you seem appropriate.

    Best,
    Hubert Hesse
