Secure connections (TLS)

The ArangoDB Kubernetes Operator will by default create ArangoDB deployments that use secure TLS connections.

It uses a single CA certificate (stored in a Kubernetes secret) and one certificate per ArangoDB server (stored in a Kubernetes secret per server).

To disable TLS, set spec.tls.caSecretName to None.

Install CA certificate

If the CA certificate is self-signed, it will not be trusted by browsers, until you install it in the local operating system or browser. This process differs per operating system.

To do so, you first have to fetch the CA certificate from its Kubernetes secret.

kubectl get secret <deploy-name>-ca --template='{{index .data "ca.crt"}}' | base64 -D > ca.crt


To install a CA certificate in Windows, follow the procedure described here.


To install a CA certificate in macOS, run:

sudo /usr/bin/security add-trusted-cert -d -r trustRoot -k /Library/Keychains/System.keychain ca.crt

To uninstall a CA certificate in macOS, run:

sudo /usr/bin/security remove-trusted-cert -d ca.crt


To install a CA certificate in Linux, on Ubuntu, run:

sudo cp ca.crt /usr/local/share/ca-certificates/<some-name>.crt
sudo update-ca-certificates
