Can no longer access Docker environment

Not sure which forum to post this in, but please move it if this is the wrong one.

I have downloaded and have had a BC docker image running yesterday. I was able to access the development environment, Windows client, web client, and was able to do so extension work. Having restarted my machine I can no longer access any of the clients. I have used PowerShell to confirm that the service is running...

I cannot connect to the database using the development environment...

...and the same goes for the other clients.

I don't really know how to go about troubleshooting this :#

Can I somehow see what services are running in this docker container? If not, how do I tell if the SQL service is running?

I get the advantages which Docker offers over a traditional virtual machine, but it just seems so hard to do simple things like check services, explore and run files, etc, etc...

As always...

    No, it does not appear to be the "zombie container" issue as reported by Freddy. I am on a newer version than he reported to fix the issue, and I was able to stop and restart the container. I am still unable to connect to the NAV development client or connect via the web or windows clients. I guess the next step is to remove and recreate the container.

    On your normal pc try running a "Docker PS" command in your shell and post the output here, this will give your the currency Status of your container.

    And this try running a Entry-NAVContainer -ContainerName XX command and check in the SQL service is running.
    Last but least try checking the event view of the Container: Get-NavContainerEventLog

    What information are your getting out of this?

    On a site note: When you are getting more used to docker and the powershell commands, and how it all works, then docker does not seems so stupid, but at first I know it seems like a lot of extra work. It will pay of in the end :smile:
    For help, do not use PM, use forum instead, perhaps other people have the same question, or better answers.

    Hi SanderDk, thanks for your reply!

    In the end I decided to delete the container and recreate it. This was quite a good exercise as I think I have got my head around this process a little better now. I pulled down a new image and created a new container.

    These posts from Freddy were invaluable....

    And also this one which isn't BC related but gives good basic Docker information....

    Once I had got my new container up and running I managed to connect to the db via SSMS running on my local machine which was great and made me feel a little more confident. I then managed to connect VSCode and reconfigure my launch.json to point to the new environment. It is actually fun when it works!!

    I was interested to see your comment with regards being able to see the services running in the Docker container...

    Where do I run this - on my local machine? And at a command prompt or in PowerShell?

    I am beginning to come to that realisation myself. I truly appreciate where Microsoft are going with the product and the technology which surrounds it, but all this change presents a quite sharp learning curve and when you feel lost and frustrated it is easy to become quite disillusioned!

    Not quite as...
