+# dockertest
+
+This package is an abstraction of several dockerized data storages using `ory/dockertest` to bootstrap a specific dockerized instance.
+
+Example postgres
+
+```go
+// create postgres instance
+pgDocker, err := dockertest.CreatePostgres(
+    dockertest.PostgresWithDetail(
+        pgUser, pgPass, pgDBName,
+    ),
+)
+
+// get connection string
+connString := pgDocker.GetExternalConnString()
+
+// purge docker
+if err := pgDocker.GetPool().Purge(pgDocker.GetResouce()); err != nil {
+    return fmt.Errorf("could not purge resource: %w", err)
+}
+```
+
+Example spice db
+
+- bootsrap spice db with postgres and wire them internally via network bridge
+
+```go
+// create custom pool
+pool, err := dockertest.NewPool("")
+if err != nil {
+    return nil, err
+}
+
+// create a bridge network for testing
+network, err = pool.Client.CreateNetwork(docker.CreateNetworkOptions{
+    Name: fmt.Sprintf("bridge-%s", uuid.New().String()),
+})
+if err != nil {
+    return nil, err
+}
+
+
+// create postgres instance
+pgDocker, err := dockertest.CreatePostgres(
+    dockertest.PostgresWithDockerPool(pool),
+    dockertest.PostgresWithDockerNetwork(network),
+    dockertest.PostgresWithDetail(
+        pgUser, pgPass, pgDBName,
+    ),
+)
+
+// get connection string
+connString := pgDocker.GetInternalConnString()
+
+// create spice db instance
+spiceDocker, err := dockertest.CreateSpiceDB(connString,
+    dockertest.SpiceDBWithDockerPool(pool),
+    dockertest.SpiceDBWithDockerNetwork(network),
+)
+
+if err := dockertest.MigrateSpiceDB(connString,
+    dockertest.MigrateSpiceDBWithDockerPool(pool),
+    dockertest.MigrateSpiceDBWithDockerNetwork(network),
+); err != nil {
+    return err
+}
+
+// purge docker resources
+if err := pool.Purge(spiceDocker.GetResouce()); err != nil {
+    return fmt.Errorf("could not purge resource: %w", err)
+}
+if err := pool.Purge(pgDocker.GetResouce()); err != nil {
+    return fmt.Errorf("could not purge resource: %w", err)
