Containerized Harvest on Mac using containerd¶

Harvest runs natively on a Mac already. If you need that, git clone and use GOOS=darwin make build.

This page describes how to run Harvest on your Mac in a containerized environment (Compose, K8, etc.) The documentation below uses Rancher Desktop, but lima works just as well. Keep in mind, both of them are considered alpha. They work, but are still undergoing a lot of change.

Setup¶

We're going to: - Install and Start Rancher Desktop - (Optional) Create Harvest Docker image by following Harvest's existing documentation - Generate a Compose file following Harvest existing documentation - Concatenate the Prometheus/Grafana compose file with the harvest compose file since Rancher doesn't support multiple compose files yet - Fixup the concatenated file - Start containers

Under the hood, Rancher is using lima. If you want to skip Rancher and use lima directly that works too.

Install and Start Rancher Desktop¶

We'll use brew to install Rancher.

brew install rancher

After Rancher Desktop installs, start it Cmd + Space type: Rancher and wait for it to start a VM and download images. Once everything is started continue.

Create Harvest Docker image¶

You only need to create a new image if you've made changes to Harvest. If you just want to use the latest version of Harvest, skip this step.

These are the same steps outline on Building Harvest Docker Image except we replace docker build with nerdctl like so:

nerdctl build -f container/onePollerPerContainer/Dockerfile -t harvest:latest . --no-cache

Generate a Harvest compose file¶

Follow the existing documentation to set up your harvest.yml file

Create your harvest-compose.yml file like this:

docker run --rm \
  --entrypoint "bin/harvest" \
  --volume "$(pwd):/opt/temp" \
  --volume "$(pwd)/harvest.yml:/opt/harvest/harvest.yml" \
  ghcr.io/netapp/harvest \
  generate docker full \
  --output harvest-compose.yml # --image tag, if you built a new image above

Combine Prometheus/Grafana and Harvest compose file¶

Currently nerdctl compose does not support running with multiple compose files, so we'll concat the prom-stack.yml and the harvest-compose.yml into one file and then fix it up.

cat prom-stack.yml harvest-compose.yml > both.yml

# jump to line 45 and remove redundant version and services lines (lines 45, 46, 47 should be removed)
# fix indentation of remaining lines - in vim, starting at line 46
# Shift V
# Shift G
# Shift .
# Esc
# Shift ZZ

Start containers¶

nerdctl compose -f both.yml up -d

nerdctl ps -a
