docker-compose up -d doesn't work

[Antonytm]

Steps to reproduce:

1. Switch to master or develop branch
2. Initialize environment .\init.ps1 -LicenseXmlFile c:\license\license.xml
3. cd custom-images\docker
4. Run .\clean.ps1 to make sure that there are no artifacts from previous times
5. cd custom-images
6. run docker-compose up -d

Expected result: containers up and running Actual result:

Creating docker-examples_mssql_1 ... done
Creating docker-examples_mssql-init_1 ... done
Creating docker-examples_solr-init_1  ... done

I ignore traefik as it will be unhealthy if at least one container is unhealthy

Investigations:

1. run docker logs 6b2cc5dcc865 (xdbsearchworker)

Error present in logs:

It looks like there is an issue with solr-init image configuration on master branch. Folder custom-images\docker\data\solr is not populated with Solr cores. However, I expect that it should be populated. I expect that there should be present Solr cores configurations, e.g.: sitecore_marketingdefinitions_master_shard1_replica_n1, sitecore_marketingdefinitions_web_shard1_replica_n1, sitecore_web_index_shard1_replica_n1, etc.

I have switched to v10.1.0.1 tag and everything works there. Solr cores folder is populated. Containers start with no errors. Sitecore is up and running.

I dug into Strart.ps1>Download-SolrConfig.ps1

There is an function Download-FileItem

function Download-FileItem {
    param(
        [string]$SolrEndpoint,
        $FileItem,
        [string]$OutPath
    )
    Write-Host "Downloading '$($FileItem.data.title)' file"
    $fileContent = (Invoke-RestMethod -Uri "$SolrEndpoint/$($FileItem.data.attr.href)" -Credential (Get-SolrCredential)).znode.data
    #File content should have "UTF-8 without BOM" encoding
    [System.IO.File]::WriteAllLines("$OutPath\$($FileItem.data.title)", $fileContent)
}

It downloads files from ZooKeeper response: The problem is that the ZooKeeper response from 8.4.0 to 8.8.2 was changed! http://localhost:8984/solr/admin/zookeeper?detail=true&path=/configs/_default&jwt=json

It means that for solr-init images for 10.2.0-ltsc2019 for XP and XM Download-FileItem function should be changed to:

function Download-FileItem {
    param(
        [string]$SolrEndpoint,
        $FileItem,
        [string]$OutPath
    )
    Write-Host "Downloading '$($FileItem.title)' file"
    $fileContent = (Invoke-RestMethod -Uri "$SolrEndpoint/$($FileItem.attr.href)" -Credential (Get-SolrCredential)).znode.data
    #File content should have "UTF-8 without BOM" encoding
    [System.IO.File]::WriteAllLines("$OutPath\$($FileItem.title)", $fileContent)
}
