About

Datapipe is a data processing pipeline that (currently) extracts audio clips from youtube videos and generates two transcription candidates with a Vosk (Kaldi) and a Wav2Vec2 model. The goal of the software is to ease the generation of datasets for ASR by automatically extracting and processing large audio sources.

Datapipe workflow

Setup cluster

Install k3s

curl -sfL https://get.k3s.io | sh -s - --write-kubeconfig-mode 644
# Check for Ready node,takes maybe 30 seconds
k3s kubectl get node
#Create alias for Kubectl
mkdir -p ~/.kube/ && sudo  cp /etc/rancher/k3s/k3s.yaml ~/.kube/config && 
sudo chown $USER:$USER ~/.kube/config && chmod 600 ~/.kube/config && export KUBECONFIG=~/.kube/config

Install kustomize

curl -s \
"https://raw.githubusercontent.com/kubernetes-sigs/kustomize/master/hack/install_kustomize.sh"  | bash  && \
sudo mv kustomize /usr/local/bin/

Create namespace

kubectl create namespace assistent

Encode secret password

#Get BASE64 encoded password
echo -n "password123#$" | base64 -i -

Create secret file and paste encoded password (k8s/postgresql/secret.yaml) As a recommendation keep POSTGRES_USER variable set to default (datapipe)

apiVersion: v1
kind: Secret
metadata:
  namespace: assistent
  name: datapipe-db-secret
data:
  POSTGRES_USER: "ZGF0YXBpcGU="
  POSTGRES_PASSWORD: "cGFzc3dvcmQxMjMjJA=="

Deployment

make deploy 

Start using datapipe

Access to any pod that was set up using projecteaina/datapipe image (example: converter-, fetcher-.. )

kubectl -n assistent exec -it fetcher-YOUR_POD_ID bash

Using the cli add new channel

python -m cli add-channel https://www.youtube.com/user/gencat/

Setup development environment

Okteto allows you to develop inside a container. When you run okteto up your Kubernetes deployment is replaced by a development container that contains your development tools. Learn more about Okteto

Install okteto

curl https://get.okteto.com -sSfL | sh

In the case that your cluster setup is not local, please set the KUBECONFIG env variable to the path of your kube config file.

#Example for setting KUBECONFIG generated by goteleport to access remote cluster
export KUBECONFIG=${HOME?}/teleport-kubeconfig.yaml

If you are using a local cluster setup then run next command

mkdir -p ~/.kube/ && sudo  cp /etc/rancher/k3s/k3s.yaml ~/.kube/config && 
sudo chown $USER:$USER ~/.kube/config && chmod 600 ~/.kube/config && export KUBECONFIG=~/.kube/config

Select and start development container

okteto up
