}How to configure for local storage
You can configure multiple directories to be accessed by the jnotebook-viewer at the same time. Depending on your preference, you can set it as list or dict.
1. "list" type
"directories": [
"/path/foo/bar/1",
"/path/foo/bar/2"
]
You can access it like:
http://localhost:9088/0
http://localhost:9088/1
2. "dict" type
"directories": {
"a": "/path/foo/bar/1",
"b": "/path/foo/bar/2"
}
You can access it like:
http://localhost:9088/a
http://localhost:9088/b
3. single directory
"directories": "/path/foo/bar/1"
You can access it like:
http://localhost:9088/ANY
How to configure for S3 storage
You can configure multiple buckets to be accessed by the jnotebook-reader at the same time. Depending on your preference, you can set it as list or dict.
1. "list" type
"buckets": [
"bucket_name_1",
"bucket_name_2"
]
You can access it like:
http://localhost:9088/0
http://localhost:9088/1
2. "dict" type
"buckets": {
"a": "bucket_name_1",
"b": "bucket_name_2"
}
You can access it like:
http://localhost:9088/a
http://localhost:9088/b
3. single bucket
"buckets": "bucket_name_1"
You can access it like:
http://localhost:9088/ANY
How to configure with environment variables
You can set configuration through environment variables. if environment variables set, the configuration file will be overwritten accordingly.
# Storage type, local or s3, default is local
JNOTEBOOK_READER_STORAGE_TYPE = "local"
# s3 endpoint, only for s3 storage type
JNOTEBOOK_READER_S3_ENDPOINT = ""
# s3 access key, only for s3 storage type
AWS_ACCESS_KEY_ID = ""
# s3 secret key, only for s3 storage type
AWS_SECRET_ACCESS_KEY = ""
# s3 bucket name, could set multiple, separated by ',' only for s3 storage type
JNOTEBOOK_READER_S3_BUCKET_NAME = ""
# local directories, could set multiple, separated by ',' only for local storage type
JNOTEBOOK_READER_DIR = ""♌ API Spec

♍ Production
If you want to release jnotebook_reader as a production service, it is recommended that you install waitress-serve to manage your service.
git clone https://github.com/line/jnotebook-reader
cd jnotebook-reader
pip install -r requirements.txt
waitress-serve --call --listen=:9088 'app:create_app' &♒ Docker
docker build -t jnotebook_reader -f docker/Dockerfile .
docker run -p 9088:9088 \
-e JNOTEBOOK_READER_SERVER_PORT="9088" \
-e JNOTEBOOK_READER_STORAGE_TYPE="s3" \
-e JNOTEBOOK_READER_S3_ENDPOINT="S3_ENDPOINT" \
-e AWS_ACCESS_KEY_ID="S3_ACCESS_KEY" \
-e AWS_SECRET_ACCESS_KEY="S3_SECRET_KEY" \
-e JNOTEBOOK_READER_S3_BUCKET_NAME="S3_BUCKET_NAME_1,S3_BUCKET_NAME_2" \
-it --rm jnotebook_reader♓ Kubernetes
# Rollout jnotebook_reader deployment on Kubernetes cluster ( all resources are created in jnotebook-reader namespace )
kubectl apply -f docker/deployment.yml
# Get jnotebook_reader port
The examples deploy a NodePort service, so you have to check for the port it is mapped to:
kubectl get svc -n jnotebook-reader
Use the second port you find in the output to access jnotebook_reader, for instance:
NAME TYPE CLUSTER-IP EXTERNAL-IP PORT(S) AGE
jnotebook-reader-svc NodePort 172.19.66.29 <none> 9088:30693/TCP 25s
Type in browser -> http://{kubernetes_cluster_ip}:30693
# Destroy all resources
kubectl delete ns jnotebook-reader☮️ Contributing
