Helm chart for multi-john

Using this helm chart, you can run multi-john on a Kubernetes cluster. Based on kompose originally (some unnecessary remnants probably remain in manifests under templates).

Usage

tldr

helm install multi-john . \
    --namespace <namespace> \
    --set="multijohn.node.johnFile.input=$(echo a5b432ee0307be7fa23aa00461f54eee34ba9d45251b5504567d37a8da339dff | base64)" \
    --set="multijohn.node.johnFlags=--format=raw-sha256" \
    --set="multijohn.totalNodes=5"
kubectl port-forward -n <namespace> howdy-<id> 8080:8080
curl localhost:8080

How it works

1. Configure values.yaml
   • .multijohn.node.johnFile.input should contain the base64 contents of your file to pass to john.
   • Make sure to pass the appropriate .multijohn.node.johnFlags to tell john what kind of hash it need to process.
   • You will probably want to set the .totalNodes. The chart will spawn one pod per node specified.
2. Install the chart;

kubectl create namespace <namespace>
helm install <name> . -n <namespace> --values values.yaml
# Check the Makefile for this too. `make install`

3. Port-forward howdy and start polling to get results;

kubectl port-forward -n <namespace> howdy-<id> 8080:8080
watch "curl -s localhost:8080 | jq"

4. Once you're satisfied with the results (don't forget to save them), you can uninstall the chart;

helm uninstall <name> -n <namespace>
# Check Makefile for this too. `make uninstall`
