upstream sent too big header while reading response header from upstream

[deonash]

Hello Guys,

I am getting upstream sent too big header while reading response header from upstream, client: 172.18.0.1, error while accessing the upstream via apisix gateway. ( created simple route and upstream[https] )

here is the related thread : #4162

Its very high level, as a beginner i am finding it difficult to make those changes in APISIX docker source and recompile them.

tried using custom nginx conf file, but its getting overwritten

apisix:
image: apache/apisix:2.13.1-alpine
restart: always
volumes:
- ./apisix_log:/usr/local/apisix/logs
- ./apisix_conf/config.yaml:/usr/local/apisix/conf/config.yaml:ro
- ./nginx_custom/nginx.conf:/usr/local/apisix/conf/nginx.conf
depends_on:
- etcd
ports:
- "9080:9080/tcp"
- "9091:9091/tcp"
- "9443:9443/tcp"
- "9092:9092/tcp"
networks:
apisix:

Please let me know anyone has fixed this.

Adding nginx configuration directly below apisix in config.yaml solved the issue.

apisix:
node_listen: 9080 # APISIX listening port
enable_ipv6: false

allow_admin: # http://nginx.org/en/docs/http/ngx_http_access_module.html#allow
- 0.0.0.0/0 # We need to restrict ip access rules for security. 0.0.0.0/0 is for test.

admin_key:
- name: "admin"
key: xyx
role: admin # admin: manage all configuration data
# viewer: only can view configuration data
- name: "viewer"
key: xyz
role: viewer

enable_control: true
control:
ip: "0.0.0.0"
port: 9092

nginx_config:
http_configuration_snippet: |
client_header_buffer_size 4m;
large_client_header_buffers 8 4m;
proxy_buffer_size 256k;
proxy_buffers 4 512k;
proxy_busy_buffers_size 512k;

Cheers!!!

Avinash :)
