Select a REANA cluster...

$export REANA_SERVER_URL=https://reana.cern.ch/

$export REANA_ACCESS_TOKEN=XXXXXXX

...or install your own

# install kubectl 1.19+, kind 0.9+ and helm 3.0+

$sudo dpkg -i kubectl*.deb kind*.deb kubernetes-helm*.deb

# create Kubernetes cluster (or use your own!)

$wget https://raw.githubusercontent.com/reanahub/reana/maint-0.9/etc/kind-localhost-30443.yaml

$kind create cluster --config kind-localhost-30443.yaml

$wget https://raw.githubusercontent.com/reanahub/reana/maint-0.9/scripts/prefetch-images.sh

$sh prefetch-images.sh

# deploy REANA using Helm

$helm repo add reanahub https://reanahub.github.io/reana

$helm repo update

$helm install reana reanahub/reana --wait

# create an admin user

$wget https://raw.githubusercontent.com/reanahub/reana/maint-0.9/scripts/create-admin-user.sh

$sh create-admin-user.sh default reana [email protected] mysecretpassword

Run your analysis

# create new virtual environment

$virtualenv ~/.virtualenvs/myreana

$source ~/.virtualenvs/myreana/bin/activate

# install REANA client

$pip install reana-client

# create new workflow

$reana-client create -n my-analysis

$export REANA_WORKON=my-analysis

# upload input code and data to workspace

$reana-client upload ./code ./data

# start computational workflow

$reana-client start

# check its progress

$reana-client status

# list workspace files

$reana-client ls

# open interactive notebook session

$reana-client open jupyter

# download output results

$reana-client download results/plot.png
