Too long startup time?

[zengxc-1996]

when I start your docker images,It need more than 5mins to access the page;
I have a good suggestion,
change this file:
/usr/local/openjdk-11/conf/security/java.security
securerandom.source=file:/dev/random   to  securerandom.source=file:/dev/urandom,
It starts right away

Looking forward to further communication;

Seems we can just use-Dsecurerandom.source=file:/dev/urandom option in cmd. Feel free to provide PR, to add it to entrypoint.

Thanks for your help,But I didn't go well
when I run this images and add -Dsecurerandom.source to my compose file ,it's works,
but I reboot my ecs

I can't open the page;
docker logs cmak:

I don't know what to do,
it's my docker-composer.yml:

version: '3.6'
services:
  kafka_manager:
    image: hlebalbau/kafka-manager:stable
    container_name: "cmak"
    restart: always
    ports:
      - "9005:9000"
    command:
      - "-Dcmak.zkhosts=172.17.0.1:2181"
      - "-DbasicAuthentication.enabled=true"
      - "-DbasicAuthentication.username=username"
      - "-DbasicAuthentication.password=password123"
      - "-Dsecurerandom.source=file:/dev/./urandom"

@zengxc-1996 how do you deploy to ECS? Using a docker-compose file, or some other tool?

TBH, I doubt this issue is related to an old lack of entropy . I observed those delays randomly on different clusters and for me it seems like an issue in CMAK itself.

So, should we do something here, or just close?

For my understanding - this issue can't be addressed completely in initially proposed way.
I still some time observer very slow startup sometimes , quite sporadically.
With the lack of entropy - container couldn't start att all.
So I think this is rather CMAK issue with connection handling.

okay, close for now

future reader, if you have a solution, please, reopen :)
