Resource initialization

When you first deploy your Upsun project, and whenever you add a new app or service, Upsun allocates the following default resources to every container:

If you don’t want to use those default resources, you can define a different resource initialization strategy. You can also adjust those resources after your project or new container has been deployed.

For information on costs related to resource usage, see the Upsun pricing page. Note that you can keep an eye on those costs in the Console.

Define a resource initialization strategy

You can define which strategy Upsun uses to allocate resources when you first deploy your project or add a new container. The following strategies are available:

upsun push --resources-init=INITIALIZATION_STRATEGY

upsun push --resources-init=minimum

git push upsun -o resources.init=minimum

platform integration:add \
  --project PROJECT_ID \
  --type github \
  --repository OWNER/REPOSITORY \
  --token GITHUB_ACCESS_TOKEN \
  --base-url GITHUB_URL
  --resources-init INITIALIZATION_STRATEGY

upsun integration:update --resources-init=INITIALIZATION_STRATEGY

upsun integration:update --resources-init=minimum

Minimum resources

The following table shows the resources Upsun allocates to your containers when you opt for the minimum resource initialization strategy.

* The disk size is set to None when the container never uses a disk, and to 0 MB when the container doesn’t require a disk but can use one.

Actions on environments

Here is how resource allocation works on Upsun when you perform the following actions on an environment:

Environment creation

When you branch an environment to create a new child environment, the child environment inherits all the resources from its parent.

Environment merge

When you merge a child environment into a parent environment, any app or service on the child environment is merged into the parent. For the merge and deployment to be complete, you need to allocate resources to each of these newly added instances.

Environment sync

When you sync an environment, the target environment’s disk size may be smaller that the source environment’s disk size.

In this case, to ensure that the synchonization succeeds, Upsun automatically adjusts the target environment’s disk size so it matches the source environment’s disk size.
