| # Migrations | ||
|
|
||
| Users can create flag collections as yaml files within a migration directory and run flagr to insert/modify flags. | ||
| This allows for developers to create flags as deployment assets and allows for migrating flags through various environments whilst keeping keys stable. | ||
|
|
||
| Each found flag is upserted into the database. Then the flag has all segments, variants and tags removed then replaced with the new flag properties. | ||
|
|
||
| As an example, create a file named `migrations/202403030000.yaml` with the following content: | ||
| ```yaml | ||
| --- | ||
| # this is a basic flag | ||
| - key: SIMPLE-FLAG-1 | ||
| description: a toggle for just one user | ||
| enabled: true | ||
| segments: | ||
| - description: flag for just for one email [email protected] | ||
| rank: 0 | ||
| rolloutPercent: 100 | ||
| constraints: | ||
| - property: email | ||
| operator: EQ | ||
| value: '"[email protected]"' | ||
| distributions: | ||
| - variantKey: "on" | ||
| percent: 100 | ||
| - rank: 1 | ||
| rolloutPercent: 100 | ||
| constraints: [] | ||
| distributions: | ||
| - variantKey: "off" | ||
| percent: 100 | ||
| variants: | ||
| - key: "off" | ||
| attachment: {} | ||
| - key: "on" | ||
| attachment: {} | ||
| entityType: User | ||
| dataRecordsEnabled: true | ||
|
|
||
| ``` | ||
|
|
||
| ```shell | ||
| $ flagr -m | ||
| INFO[0146] 1 new migrations completed (1 total) | ||
| ``` | ||
| Once the application is ran, flagr will scan the migration files, insert them into the db and shut down. | ||
|
|
||
| ### Config | ||
| Location of yaml configs can be set with either argument or env var. | ||
| ``` | ||
| FLAGR_MIGRATION_PATH=./migrations/ ./flagr -m | ||
| ./flagr -m --migrationPath=`pwd`/migrations | ||
| ``` |
