psviderski/uncloud v0.6.0

on GitHub

Highlights

• Extended Docker Compose support: 🎉 Added support for deploying services from Docker Compose files with volumes, environment variables, resource limits, and more.
• New volume management: Create, list, inspect, and remove volumes across your cluster with the new volume command.
• Context management: Switch between different cluster contexts using the new ctx command.
• Improved resource control: Specify CPU, memory, and environment variables for containers.

Breaking changes

• Configuration format changed from TOML to YAML
• --cluster flag renamed to --context
• Revised machine placement system using --machine flag instead of machine filters

Features and improvements

• Volume management:

  • Full volume lifecycle management with uc volume create/ls/inspect/rm
  • Support for volume scheduling across machines based on service constraints
  • Automatic volume creation for services that need them

• Compose support:

  • Deploy services from Docker Compose files with uc deploy
  • Support for volume, bind, and tmpfs mounts
  • Environment variables and resource constraints

• Context management:

  • Switch between multiple cluster contexts with uc ctx
  • Manage multiple clusters with uc ctx ls and uc ctx use

• Container improvements:

  • CPU and memory limits with --cpu and --memory flags
  • Environment variables via -e flag
  • Container user via -u flag
  • Log driver configuration

• Machine management:

  • Support for selecting specific uncloud version during initialising (machine init) or adding (machine add) a new machine to the cluster
