Problems with docker attach #3337

Closed sorsted closed 7 months ago

Describe the issue

I installed Business Central in a container using Docker Engine (not Docker Desktop), mostly following this guide: https://www.youtube.com/watch?v=lPKkKbLaQ9Y

The PowerShell script for the installation and its output can be found below.

I would then like to be able to run commands in the container. So I do docker start bcserver, which works fine, and then follow up with docker attach bcserver. Then nothing happens, and no output ever being produced. So I press Ctrl + C to stop the process and then repeat both docker start bcserver and docker attach bcserver. This time, something does happen, namely:

Container Total Physical Memory is 62.8Gb
Container Free Physical Memory is 39.4Gb

Initialization took 9 seconds
Ready for connections!

And that’s it. No more output is ever produced, and pressing keys yields no reaction.

I also tried docker exec -it bcserver bash, but this just yields:

container e485fea63a7b5b47189e20449de33a313b6c42fdb8415518d45ed94b54966e7e encountered an error during hcs::System::CreateProcess: bash: failure in a Windows system call: The system cannot find the file specified. (0x2)

Scripts used to create container and cause the issue

$containerName = 'bcserver'
$password = 'P@ssw0rd'
$securePassword = ConvertTo-SecureString -String $password -AsPlainText -Force
$credential = New-Object pscredential 'admin', $securePassword
$auth = 'UserPassword'
$artifactUrl = Get-BcArtifactUrl -type 'Sandbox' -country 'dk' -select 'Latest'

    -containerName $containerName `
    -credential $credential `
    -auth $auth `
    -artifactUrl $artifactUrl `
    -usessl -installCertificateOnHost `

Docker attach attaches the the main loop, which is a message pump - nothing really to do there. The reason for your docker exec -it bcserver bash not working is that bash doesn't exist. Use PowerShell instead - docker exec -it bcserver powershell Current generic images use powershell 5 - pwsh is also not installed.

You can also use the BcContainerHelper command Invoke-ScriptInBcContainer, which pre-loads all BC CmdLets, Example:

Invoke-ScriptInBcContainer -containername bcserver -scriptblock {
    get-navserverinstance
}
