Upgrade

When to use this procedure

You can use this procedure to upgrade HAProxy Kubernetes Ingress Controller anywhere you have installed it using Helm. This includes on-premises installations as well as installations in cloud providers.

If you installed the ingress controller using Helm, you can use the helm upgrade command to upgrade to the latest version. Helm will initiate a rolling update, waiting for the new ingress controller pods to start up before terminating the old ingress controller pods. That way, there is no interruption in service.

To perform the upgrade:

When calling helm upgrade, pass all arguments that you previously used when installing the ingress controller. Helm will install the latest version.

nix
helm upgrade haproxy-kubernetes-ingress haproxytech/kubernetes-ingress \
  --create-namespace \
  --namespace haproxy-controller
nix
helm upgrade haproxy-kubernetes-ingress haproxytech/kubernetes-ingress \
  --create-namespace \
  --namespace haproxy-controller

You can provide a specific version of the Helm chart you wish to use if you want to upgrade to a version that is not the latest version.

To see the list of available versions (and their corresonding Helm chart version) use the helm search repo command with the --versions flag to list all of the available versions of the Helm chart:

nix
helm search repo haproxytech/kubernetes-ingress --versions
nix
helm search repo haproxytech/kubernetes-ingress --versions

To upgrade to a specific version of the HAProxy Kubernetes Ingress Controller, use the --version parameter and provide the version of the Helm chart that corresponds to that version. For example, to install version 1.10.9, we will specify the Helm chart version as 1.34.1:

nix
helm upgrade haproxy-kubernetes-ingress haproxytech/kubernetes-ingress \
  --create-namespace \
  --namespace haproxy-controller \
  --version 1.34.1
nix
helm upgrade haproxy-kubernetes-ingress haproxytech/kubernetes-ingress \
  --create-namespace \
  --namespace haproxy-controller \
  --version 1.34.1
