helm upgrade seçeneği

Giriş

Açıklaması şöyle

Helm install creates a special type of Kubernetes secret that holds release information and deploys the chart if not present. If Chart is present on the cluster then it will fail. To upgrade any deployed chart release, you need to use an upgrade command. Helm provides another option for chart deployment which verifies the Chart is present or not, in case of yes then it will upgrade the chart or it will install the chart.

Açıklaması şöyle

helm upgradee <release-name> <path-to-chart> — upgrade earlier release with updated chart

helm upgrade <release-name> <path-to-chart> –f <path-to-yaml-file> — upgrade earlier release with updated chart and configuration provide in yaml file

helm upgrade <release-name> helm-chart-demo –set <key-name> = <value>- upgrade earlier release with updated chart and updated value with –set flag
