And if your remote server or virtual machine only has 3 GB of RAM, trying to load more than 4 GB of RAM will cause problems. 🚨

### Multiple Processes - An Example

In this example, there's a **Manager Process** that starts and controls two **Worker Processes**.

So, if your application consumes a lot of memory (for example with machine learning models), and your server has a lot of CPU cores **but little memory**, then your container could end up trying to use more memory than what is available, and degrading performance a lot (or even crashing). 🚨

### Create a `Dockerfile`

Here's how you would create a `Dockerfile` based on this image:

```Dockerfile

ifneq ($(findstring google,$(HOSTNAME)),)
warning+=Googlers: go/installdocker\#the-version-of-docker-thats-installed-is-old-eg-1126
endif
# The old docker issue manifests as not being able to run *any* binary. So we can test
# by trying to run a trivial program and ensuring it actually ran. If not, emit our warning.
# Note: we cannot do anything like $(shell docker version) to check, since that would also fail.
CAN_RUN := $(shell echo "can I run echo")
