ros2 package is giving error running it in a docker

[marknabil]

running the humble controller inside a docker gives the following error

[spawner-4] [dsr01.spawner_dsr_controller2] [INFO///1728055365.812337257]: waiting for service /dsr01/controller_manager/list_controllers to become available...

I check if the docker of emulator is created or not, and I find it created successfully.

@marknabil I am not how ur running the container . I would recommend this method , it worked for me

1. git clone repo in src and open doossanrobot2 folder
   2, open the folder in vs code
2. ctrl+shift+p --> type rebuild and reopen in container( this will work once u has docker extension)
3. now the best part is your inside container and you can add your code inside container . Also doosan dockerfile is attaached as volume so you can create your files too inside .
   I think this method might resolve some issue while building docker container . if its not an issue of container check internet and maek sure u permit permmsion for docker in docker then only emulator will run .
   let me know if anything helped
