 - `tolerations`: List of tolerations to be added to the buildkit service Pods. This list of tolerations will be applied in conjunction with any tolerations set in [`tolerations.buildPool`](self-hosted/helm-configuration.mdx#tolerations) until deprecation of `tolerations.buildPool`. If not set, the buildkit Pods will inherit the tolerations list set in [`globals.tolerations.okteto`](self-hosted/helm-configuration.mdx#globals).
 - `nodeSelectors`: Dictionary of node selectors to be added to the buildkit service Pods. This helps you match Pods to nodes whose labels match the node selector. This list of node selectors will be applied in conjunction with the node selectors set by [`tolerations.buildPool`](self-hosted/helm-configuration.mdx#tolerations) until deprecation of `tolerations.buildPool`.

This can be useful in complex build environments where security, efficiency, and consistency are priorities
