Support ASF Header in .md and .sh files for scancode (#292) * Fix EOL issues in .md files. * Fix missing ASF License, EOL issues in .sh files.
A performant API Gateway based on Openresty and NGINX.
This project is currently considered beta stage, Large swaths of code or APIs may change.
docker run -p 80:80 -p <managedurl_port>:8080 -p 9000:9000 \ -e PUBLIC_MANAGEDURL_HOST=<managedurl_host> \ -e PUBLIC_MANAGEDURL_PORT=<managedurl_port> \ -e REDIS_HOST=<redis_host> \ -e REDIS_PORT=<redis_port> \ -e REDIS_PASS=<redis_pass> \ openwhisk/apigateway:latest
The Gateway can sync its configuration with a remote folder in the cloud such as Amazon S3, Google Cloud Storage, IBM Cloud Object Storage, Dropbox, and many others. The configuration is monitored for changes, and when a file is changed, the Gateway is reloaded automatically. This is very useful to gracefully update the Gateway on the fly, without impacting the active traffic; if the new configuration is invalid, the Gateway doesn't break, running with the last known valid configuration.
This feature is enabled by configuring a few environment variables:
REMOTE_CONFIG- the location where the configuration should be synced from. I.e.
s3://api-gateway-config. The remote location is synced into is
/etc/api-gateway. The default configuration is found in this project's root folder.
REMOTE_CONFIG_SYNC_INTERVAL- how often to check for changes in the remote location. The default value is
REMOTE_CONFIG_RELOAD_CMD- which command to execute in order to reload the Gateway. The default value is:
api-gateway -s reload
Syncing is done through rclone sync.
rclone has a rich set of options such as what to exclude when syncing, or what to include. An important configuration is
--config, pointing to the config file in
/root/.config/rclone/rclone.conf. The Gateway should be started with
/root/.config/rclone folder mounted so that
rclone.conf is present. To generate a new
rclone configuration simply execute:
docker run -ti --rm --entrypoint=rclone -v `pwd`/rclone/:/root/.config/rclone/ openwhisk/apigateway config
This runs an interactive
rclone config command and stores the resulted configuration in
To test this locally, simulate a remote folder using a local location, by mounting it in
/tmp folder as follows:
docker run -ti --rm -p 80:80 \ -v `pwd`:/tmp/api-gateway-local -e REMOTE_CONFIG="/tmp/api-gateway-local" \ -e REDIS_HOST=redis_host -e REDIS_PORT=redis_port openwhisk/apigateway
Then make changes to any configuration file ( i.e.
api-gateway.conf ), save it, then watch as the Gateway reloads the updated configuration automatically.
To build the docker image locally use:
To Run the Docker image
make docker-run PUBLIC_MANAGEDURL_HOST=<mangedurl_host> PUBLIC_MANAGEDURL_PORT=<managedurl_port> \ REDIS_HOST=<redis_host> REDIS_PORT=<redis_port> REDIS_PASS=<redis_pass>
First install the necessary dependencies:
Then, run the unit tests:
