In order to get cypress running on AWS lambda, there are a few issues that you need to work through.

I've put together a full minimal example of how to get cypress running on lambda.

I'll cover the highlights of what is involved.

Lambda runs with a read-only file system, using an unprivileged user, and no ipc or shared memory device.

The only writable location is the /tmp directory, which has 512mb of space by default.

• Cypress needs to be installed at a location that is readable by non-privileged users.
• In order to get electron to work, it's binary needs to be patched so it doesn't try and use /dev/shm
• Cypress requires that project directory is writable, which means that you need to copy the project into the /tmp directory, or patch cypress so it won't crash.
• We need to pass a bunch of flags to chromium, to disable features that use things like GPU, and shared memory, which aren't available on lambda.
