Local usage

You can use package in your condo monorepo fork by running the following command to build package:

yarn workspace @open-condo/migrator build

And then the one to run it:

npx @open-condo/migrator --help

Remote usage

Without installation

You can use migrator on remote instances without installing additional packages by running:

npx @open-condo/migrator@latest --help

With installation

Or alternatively you can install it with:

yarn add -D @open-condo/migrator

And then run with:

npx @open-condo/migrator --help

How to run migration commands

List of commands and arguments

You can use the following command to explore list of all available commands:

npx @open-condo/migrator --help

Then you can explore command arguments / description by running the following:

npx @open-condo/migrator <command> --help

Running command locally

You can migrate whole monorepo by running command from monorepo root. For example:

npx @open-condo/migrator add-apps-kv-prefixes

Or you can more precisely run it for single / multiple apps:

npx @open-condo/migrator add-apps-kv-prefixes -f condo address-service

Running command on remote environments

You can also run migration commands on deployed applications where access .env files is not possible, since environment variables are passed from external tools and apps are deployed "one per pod".

For this scenarios you can migrate single app at a time by running commands like this:

REDIS_URL=redis://remote_user:*******@127.0.0.1:6379/6 npx @open-condo/migrator add-apps-kv-prefixes -f condo

NOTE: You can remove REDIS_URL=** part if environment variables are already set (from export or other external tool)

You can also run migrator from specific app folder instead of using --filter arg:

cd apps/condo
npx @open-condo/migrator add-apps-kv-prefixes

Available commands

add-apps-kv-prefixes

This command will add keyPrefix to all your keys of your KV database (Redis).

For example, for condo app new keys will look like this:

• my_key -> condo:my_key
• sess:asd123ghj -> condo:sess:asd123ghj
• bull:low:importMeters:123 -> {condo:bull:low}:importMeters:123
