 Running a full node typically requires ~500G of SSD storage, 8G of RAM and 4-8 CPU threads (depending on clock
 frequency). Light clients have much lower hardware requirements.

 existing build pipeline. If you need Dockerfile examples, you can take a look at our devnet deployment.

 If you deploy using a custom pipeline, you need to set the `CAP_IPC_LOCK` capability on the binary (e.g. doing the
 equivalent to `sudo setcap cap_ipc_lock=+ep`) to allow it to lock its memory pages to prevent them from being paged out.
