# Erasure code sizing guide

## Toy Setups

Capacity constrained environments, MinIO will work but not recommended for production.

		host, port, err := net.SplitHostPort(addr)
		if err != nil {
			return nil, err
		}

		if net.ParseIP(host) != nil {
			// For IP only setups there is no need for DNS lookups.
			return baseDialCtx(ctx, "tcp", addr)
		}

## Outside of Kubernetes

The annotation above configures a volume mount and configures Istio to use it.
When running outside of Kubernetes or in custom setups, similar functionality can be achieved by setting the `ISTIO_BOOTSTRAP_OVERRIDE` variable pointing to a file containing the custom bootstrap.

## Cleanup

```bash
kubectl delete -f custom-bootstrap.yaml

        block.releaseAll()
        build.waitForFinish()

        then:
        noExceptionThrown()

        cleanup:
        cacheAccess?.close()
    }

    /**
     * This setups a {@link FixedSharedModeCrossProcessCacheAccess} that does initially not see that the cache is already initialised

	if err := ctx.GetResource(&out); err != nil {
		return nil, err
	}
	return out, nil
}

// Setup is a utility function for creating a namespace in a test suite.
func Setup(ns *Instance, cfg Config) resource.SetupFn {
	return func(ctx resource.Context) (err error) {
		*ns, err = New(ctx, cfg)
		return
	}
}

// Getter for a namespace Instance
type Getter func() Instance

	// Register peer REST router only if its a distributed setup.
	registerPeerRESTHandlers(router, globalGrid.Load())

	// Register bootstrap REST router for distributed setups.
	registerBootstrapRESTHandlers(globalGrid.Load())

	// Register distributed namespace lock routers.
	registerLockRESTHandlers()

	// Add grid to router

## Creating a hotfix branch

Customers in MinIO are allowed LTS on any release they choose to standardize. Production setups seldom change and require maintenance. Hotfix branches are such maintenance branches that allow customers to operate a production cluster without drastic changes to their deployment.
