Custom Domain Name
SlackerNews must be configured with a fully qualified domain name. The application uses Slack events and Slack requires that connections are made over trusted TLS (https) connections. In order to meet this requirement, you'll need to provide a domain name and TLS keypair that is commonly trusted.
You'll need to determine this domain before you get started in order to set up the Slack app and properly configure the Helm chart or virtual machine configuration. Generally, it's advised to configure SlackerNews with the DNS record, then determine the IP address that is being used, and add the DNS record last.
Bring Your Own domain
The easiest solution to deploy the Helm chart to an existing Kubernetes cluster that supports Load Balancer service types. This will provision an IP address at installation time, and you can then create a CNAME record pointing to the LoadBalancer address of the
If you use a different service type, you will be responsible for routing traffic into the
slackernews-nginx service. Common solutions here include using a NodePort or ClusterIP service, and setting up your own load balancer or gateway to allow traffic to route into the application.
For example, in this example, SlackerNews was deployed using Helm and the option:
After installation, the LoadBalancer is created:
kubectl get svc -n slackernews slackernews-nginx NAME TYPE CLUSTER-IP EXTERNAL-IP PORT(S) AGE slackernews-nginx LoadBalancer 10.100.198.89 a6fa4c573a4dc490dbd3415319275340-126097229.us-east-1.elb.amazonaws.com 80:31698/TCP 14m
In this example the DNS administrator must create a CNAME from
In addition to DNS, SlackerNews requires that trusted TLS connections are used to connect from Slack. When deploying via Helm, the two parameters
service.tls.key are required. These should be set to the contents of the cert and key, respectively.
export SLACKERNEWS_CERT=`cat ./certificate.pem` export SLACKERNEWS_KEY=`cat ./key.pem` helm install \ ... <other params removed> \ --set service.tls.cert="$SLACKERNEWS_CERT" \ --set service.tls.key="$SLACKERNEWS_KEY"
