Description

This PR changes the container name generation for Docker-based sbin scripts to use the full UUID
instead of only the last 4 characters.

Before: clp-compression-a1b2 (last 4 chars of UUID, ~65,536 unique values)
After: clp-compression-989c2953-3111-41d2-a068-22d2dbf29c41 (full UUID, virtually unlimited)

Motivation

The previous implementation used only the last 4 hex characters of a UUID, providing only 65,536 (16^4) unique values. This could lead to container name collisions in:

• High-volume production environments with many concurrent jobs
• Rapid successive job submissions
• Long-running deployments accumulating many jobs over time

Impact Assessment

Affected Scripts

The following Docker-based sbin scripts use generate_container_name():

Affected Config Files

Each script also calls dump_container_config() with get_container_config_filename(container_name)
to create a temporary config file in var/log/:

These files are created before native container execution and used to pass configuration into the
native container.

Validation performed

1. Build and start CLP:

   task
   cd build/clp-package
   ./sbin/start-clp.sh

2. Test compress.sh - verify container name and config file both use full UUID:

   ./sbin/compress.sh --timestamp-key timestamp ~/samples/postgresql.jsonl &
   # Poll until container/config file appears (they are cleaned up after script exits)
   for i in {1..20}; do
       CONTAINER=$(docker ps --filter "name=clp-compression" --format "{{.Names}}")
       CONFIG=$(ls var/log/.clp-compression-*-config.yaml 2>/dev/null)
       if [[ -n "$CONTAINER" && -n "$CONFIG" ]]; then
           echo "$CONTAINER"; echo "$CONFIG"; break
       fi
       sleep 0.2
   done

   Output:

   clp-compression-bec69303-7c35-47eb-bf3e-f83c10244f4c
   var/log/.clp-compression-bec69303-7c35-47eb-bf3e-f83c10244f4c-config.yaml
   

   Both the container name and config file use the same full UUID.

3. Test search.sh:

   ./sbin/search.sh "ERROR" &
   for i in {1..20}; do
       CONTAINER=$(docker ps --filter "name=clp-search" --format "{{.Names}}")
       CONFIG=$(ls var/log/.clp-search-*-config.yaml 2>/dev/null)
       if [[ -n "$CONTAINER" && -n "$CONFIG" ]]; then
           echo "$CONTAINER"; echo "$CONFIG"; break
       fi
       sleep 0.2
   done

   Output:

   clp-search-1495aa61-9206-45a0-a551-9f27e27950c7
   var/log/.clp-search-1495aa61-9206-45a0-a551-9f27e27950c7-config.yaml
   

4. Test admin-tools/archive-manager.sh:

   ./sbin/admin-tools/archive-manager.sh find &
   for i in {1..20}; do
       CONTAINER=$(docker ps --filter "name=clp-archive-manager" --format "{{.Names}}")
       CONFIG=$(ls var/log/.clp-archive-manager-*-config.yaml 2>/dev/null)
       if [[ -n "$CONTAINER" && -n "$CONFIG" ]]; then
           echo "$CONTAINER"; echo "$CONFIG"; break
       fi
       sleep 0.2
   done

   Output:

   clp-archive-manager-84b0f179-1497-4860-81b7-82fcd93fa09b
   var/log/.clp-archive-manager-84b0f179-1497-4860-81b7-82fcd93fa09b-config.yaml
   

5. Test admin-tools/dataset-manager.sh:

   ./sbin/admin-tools/dataset-manager.sh list &
   for i in {1..20}; do
       CONTAINER=$(docker ps --filter "name=clp-dataset-manager" --format "{{.Names}}")
       CONFIG=$(ls var/log/.clp-dataset-manager-*-config.yaml 2>/dev/null)
       if [[ -n "$CONTAINER" && -n "$CONFIG" ]]; then
           echo "$CONTAINER"; echo "$CONFIG"; break
       fi
       sleep 0.2
   done

   Output:

   clp-dataset-manager-1447b279-bc73-44ab-a4ba-69925f767c8c
   var/log/.clp-dataset-manager-1447b279-bc73-44ab-a4ba-69925f767c8c-config.yaml
   

6. Stop CLP:

   ./sbin/stop-clp.sh

   Output:

• Bug Fixes
  • Improved container name uniqueness by using full identifiers instead of abbreviated versions, reducing the risk of naming collisions.
