Building the application

“Building” in this context compiles your application into RISC-V architecture and consequently builds a Cartesi machine containing your application. This architecture enables computation done by your application to be reproducible and verifiable.

With the Docker engine running, change the directory to your application and build by running:

cartesi build

The successful execution of this step will log this in your terminal:

         .
        / \
      /    \
\---/---\  /----\
 \       X       \
  \----/  \---/---\
       \    / CARTESI
        \ /   MACHINE
         '

Memory

To change the default memory size for the Cartesi Machine, you can personalize it by adding a specific label in your Dockerfile.

The line below lets you define the memory size in megabytes (MB):

LABEL io.cartesi.rollups.ram_size=128Mi

environment variables

You can create a .cartesi.env in the project's root and override any variable controlling the rollups-node.
