Nginx bouncer error: request failed: bad uri: ${CROWDSEC_LAPI_URL}

[usma0118]

What happened?

Nginx throws error:
[Crowdsec] bouncer error: request failed: bad uri: ${CROWDSEC_LAPI_URL}/v1/decisions?ip=*.*.*.*, client: *.*.*.*, server: [redacted], request: "GET /startpage/ HTTP/2.0", host: "[redacted]", referrer: "[redacted]"

What did you expect to happen?

Should use API_URL variable as per docs.

How can we reproduce it (as minimally and precisely as possible)?

Deploy nginx bouncer on kubernetes via:

controller:
  extraVolumes:
    - name: crowdsec-bouncer-plugin
      emptyDir: {}
  extraInitContainers:
    - name: init-clone-crowdsec-bouncer
      image: crowdsecurity/lua-bouncer-plugin

      imagePullPolicy: IfNotPresent
      env:
        - name: CROWDSEC_LAPI_URL
          value: "http://crowdsec-service.watchtower.svc.cluster.local:8080" # crowdsec lapi service-name
        - name: API_URL
          value: "http://crowdsec-service.watchtower.svc.cluster.local:8080" # crowdsec lapi service-name
        - name: API_KEY
          valueFrom:
            secretKeyRef:
              name: ingress-nginx
              key: BOUNCER_KEY
        - name: BOUNCER_CONFIG
          value: "/crowdsec/crowdsec-bouncer.conf"
        - name: BAN_TEMPLATE_PATH
          value: /etc/nginx/lua/plugins/crowdsec/templates/ban.html
      # Due to https://discourse.crowdsec.net/t/problems-installing-nginx-bouncer-in-k3s/1273
      # command: ['sh', '-c', "sh /docker_start.sh; mkdir -p /lua_plugins/crowdsec/; cp -R /crowdsec/* /lua_plugins/crowdsec/"]
      command:
        [
          "sh",
          "-c",
          "apk update; apk add bash; bash /docker_start.sh; mkdir -p /lua_plugins/crowdsec/; cp -R /crowdsec/* /lua_plugins/crowdsec/",
        ]
      volumeMounts:
        - name: crowdsec-bouncer-plugin
          mountPath: /lua_plugins
  extraVolumeMounts:
    - name: crowdsec-bouncer-plugin

      subPath: crowdsec
  config:
    plugins: "crowdsec"
    lua-shared-dicts: "crowdsec_cache: 50m"
    server-snippet: |
      resolver local=on ipv6=off;

Will look into this currently it should detect the API_URL within the bash script and replace the whole configuration line.

cs-openresty-bouncer/docker/docker_start.sh

Lines 8 to 10 in 3ae4af0

	if [ "$API_URL" != "" ]; then
	sed -i "s,API_URL.*,API_URL=$API_URL," "$CROWDSEC_BOUNCER_CONFIG"
	fi

Can you check the loaded configuration location does not include duplicated API_URL keys by execing into the nginx ingress?

ok, issue is if initContainer fails due to some reason... currently that's not resulting in process failure. and system continues.
