That is, read from the values.yaml file

Modify hydrogen-namespace.yamlapiVersion: v1kind: Namespacemetadata: name: hydrogen labels: name: hydrogen---apiVersion: v1kind: Namespacemetadata: name: ingress-nginx labels: name: ingress-nginxtemplates into the project yaml file cd ~ / hydrogen/developcp hydrogen-* ~ / heml/hydrogen-chart/templates/ to build charthelm install hy hydrogen-chart

Where hy refers to the release name, and hydrogen-chart refers to the name of chart

Package charthelm package hydrogen-chart debug charthelm install hy hydrogen-chart-- debug-- dry-run delete charthelm uninstall hy or helm uninstall hy-- purge view the rendered resource file helm get manifest hy modify the image version

Modify the version value in values.yaml

Note helm upgrade hy hydrogen-chart rollback version helm history hydrogen-charthelm rollback hy 1
