I'm trying to setup open ldap in linux VM and I am using openldap server from bitnami and

As per this documentation, when i try to do the initial setup via UI (http://ip-address:8082/setup), using the password 'password', I always get the following error.
Problem: Failed to bind as cn=admin,dc=company,dc=network
Wondering if anyone help identify what'm missing here?
I am making an REST API which has a POST method which accepts a String as JSON and then sends it over RabbitMQ Topic and then a consumer is converting into entity and saving into a MySQL db.
Everything is running fine locally, but my task is to upload it on Docker and to be run online.
When I try to change "localhost" in properties with container names my Maven build fails....
How can i fix that?
I am putting my .properties:
spring.main.allow-bean-definition-overriding=true
spring.datasource.url=jdbc:mysql://localhost:3306/rabbit_messages?createDatabaseIfNotExist=true
spring.datasource.username=root
spring.datasource.password=1234

spring.rabbitmq.port = 5672
spring.rabbitmq.username = guest
spring.rabbitmq.password = guest

I am executing automation tests using Docker containers. I have to run test suites for multiple applications on the same server. But if I have same port for each selenium hub docker container then I cannot run all these suites at the same time. Thus I want to assign different ports to each selenium/hub docker container. Is there any way I can change hub container's port? Or do I need to write my own dockerfile and not use selenium/hub docker images?
My docker-compose file looks like this
version: "3"

You can change the ports using the SE_OPTS environment variable: just add
environment:
SE_OPTS: "-port <YOUR_PREFERED_PORT>"
to your docker-compose.yml and Selenium will start at <YOUR_PREFERED_PORT>.
See https://github.com/SeleniumHQ/docker-selenium#se_opts-selenium-configuration-options
According to the Dockerfile https://github.com/SeleniumHQ/docker-selenium/blob/master/Hub/Dockerfile you can set GRID_HUB_PORT
environment:
GRID_HUB_PORT: "4545"
Just do a find and replace of 4444 with whatever port you want to use. For example, use 4440 instead of 4444.

I had a situation where I was conducting automated selenium tests for two different web applications on the same Jenkins machine. I needed 2 selenium grids to be set up and running on the same machine each employing unique and distinct ports. Instead of creating docker images of my own for the hubs and nodes I changed the docker compose file for the second selenium grid to the following:
version: "3.5"
services:
hub:
image: selenium/hub
container_name: selenium_hub_nia
ports:
- "3333:4444"
networks:
- nia_bridge
environment:
GRID_MAX_SESSION: 16
GRID_BROWSER_TIMEOUT: 10000
GRID_TIMEOUT: 10000
GRID_HUB_PORT: 3333
expose:
- "3333"
chrome:
image: selenium/node-chrome
container_name: selenium_node_nia_chrome
depends_on:
- hub
environment:
- HUB_PORT_4444_TCP_ADDR=hub
- HUB_PORT_4444_TCP_PORT=3333
- NODE_MAX_SESSION=4
- NODE_MAX_INSTANCES=4
volumes:
- /dev/shm:/dev/shm
ports:
- "9003:5900"
links:
- hub
networks:
- nia_bridge
firefox:
image: selenium/node-firefox-debug
container_name: selenium_node_nia_firefox
depends_on:
- hub
environment:
- HUB_PORT_4444_TCP_ADDR=hub
- HUB_PORT_4444_TCP_PORT=3333
- NODE_MAX_SESSION=4
- NODE_MAX_INSTANCES=4
volumes:
- /dev/shm:/dev/shm
ports:
- "9004:5900"
links:
- hub
networks:
- nia_bridge
networks:
nia_bridge: {}
Three major changes in the above file:
In the hub definition :
I first mapped the port 4444 of the second selenium hub container to the host (Jenkins server) port 3333 (the first hub continues to run on 4444). This solves the error of 4444 being bound already when the first selenium hub container is running.
I also defined its GRID_HUB_PORT as 3333 and exposed that port to the containers on the network bridge named nia-bridge.
In the two services for my 2 nodes (chrome and firefox), I specified the HUB_PORT_4444_TCP_PORT as 3333 so they use the correct url to register to the hub.
This docker compose file spins up 3 containers. I made the container names unique i.e. different from the pre-existing selenium grid network that you may already have for your other web application. This is required because docker container names must be unique.
The above helped me spin up a completely distinct selenium grid with the hub and 2 nodes running on ports 3333,9003,9004 respectively of the host Jenkins server.

I have a Traefik reverse proxy which generate ACME certificate and I would like to have SSL enabled on my docker container.
In my container I have a self-signed certificate but Traefik refuse to connect to it.
