The Wallarm Node buildpack provides Wallarm WAF inside a dyno and connects NGINX to an app server via UNIX domain sockets.
This buildpack is based on
Wallarm Node does the following:
This buildpack updates automatically and installs the latest stable version of Wallarm Node.
/tmp/app-initializedwhen you are ready for traffic.
These are two setup examples. One example is for a new app; another one is for an existing application. In both cases, we are using Ruby & Unicorn. Note: this buildpack is not Ruby specific.
The Wallarm Node buildpack provides the
wallarm/bin/start-wallarm command. This command takes another command as an argument. You must pass your app server's startup command to
For example, to get Wallarm Node and Unicorn up and running:
$ cat Procfile web: wallarm/bin/start-wallarm bundle exec unicorn -c config/unicorn.rb
You can use the following environment variables:
WALLARM_USER- user at my.wallarm.com with permissions to add new nodes.
WALLARM_PASSWORD- user password.
WALLARM_MODE- WAF mode:
monitoring(default; detect but not block),
block(detect and block).
WALLARM_API_HOST- address of Wallarm API service ("api.wallarm.com" by default)
WALLARM_TARANTOOL_MEMORY- amount of memory (in GB) allocated to the postanalytics module (0.5 of total memory by default).
WALLARM_ENABLED- Disable all wallarm services if set and has value other then "yes" or "true".
Example: set your
WALLARM_MODE to the blocking mode:
$ heroku config:set WALLARM_MODE=block
Example: disable all the Wallarm features for the debug purposes:
$ heroku config:set WALLARM_ENABLED=no
You can provide your own NGINX configuration by creating a file named
nginx.conf.erb in the directory
wallarm/etc. Start by copying the buildpack's default config file.
The buildpack will not start NGINX with the Wallarm module until a file is written to
/tmp/app-initialized. Since NGINX binds to the dyno's $PORT and since $PORT determines if the app can receive traffic, you can delay NGINX accepting traffic until your application is ready to handle it. The examples below show how/when you should write the file when working with Unicorn.
