Little action plan:

• Create new server brain-up-new on vds.selectel.ru - Created with ubuntu 22.04 64bit. 512MB Memory / 20GB SSD / 1CPU
• Install docker
• install docker-compose
• Install github self-hosted runner - installed with label selectel - vds_selectel_brain-up-new
• look how to copy db from old instance - created backup from old db 2024-10-03 01:06 and copied to new instance
• switch pipelines to deploy into new instance - PR Devops/new instance #2618
• enable swap with 1GB, because 512MB is not enough for our app
• deploy new app on new instance
• update db from backup (possibly create new backup when all testing is done
• copy cert volumes from previous instance
• switch domain name from old instance to new one
• check if all works fine

started app without certs on new instance here: http://188.68.222.249/

[DmitriyStoyanov]

certificates copied, frontend with tls was started and dns records changed from old to new instance
So now https://brainup.site/ should point to new instance

[DmitriyStoyanov]

hm, after merge PR #2618 there are some errors:
https://github.com/Brain-up/brn/actions/runs/11163834931/job/31031943111
ERROR: for brn 'ContainerConfig'

[DmitriyStoyanov]

fixed by stopping locally front and backend containers and deploying it via pipeline
