Install atlas:
curl -sSf https://atlasgo.sh | shFirst of all you should run a database instance:
docker run \
--name devdb \
-e POSTGRES_PASSWORD=admin \
-e POSTGRES_USER=admin \
-e POSTGRES_DB=db \
-p 5432:5432 -d postgres:alpine3.18Import ariga.io/atlas-provider-gorm/gormschema on project:
// tools.go
//go:build tools
package main
import _ "ariga.io/atlas-provider-gorm/gormschema"Create HCL file:
data "external_schema" "gorm" {
program = [
"go",
"run",
"-mod=mod",
"ariga.io/atlas-provider-gorm",
"load",
"--path", "./models",
"--dialect", "postgres", // | mysql | sqlite | sqlserver
]
}
env "gorm" {
src = data.external_schema.gorm.url
dev = "docker://postgres/alpine3.18"
migration {
dir = "file://migrations"
}
format {
migrate {
diff = "{{ sql . \" \" }}"
}
}
}Create model:
// models/model.go
package models
import "gorm.io/gorm"
type User struct {
gorm.Model
Username string
Age uint
}Then you should migrate your database:
atlas migrate diff --env gormFeel free to change model and save diff. Then you can migrate database using following command:
atlas schema apply \
--url "postgres://admin:admin@localhost:5432/db?sslmode=disable" \
--to "file://migrations" \
--dev-url "docker://postgres/alpine3.18"
