Migrate, duplicate or rename a stack
To migrate, duplicate, or rename a stack, open your environment, go to Stacks, and select the stack you want to change.
Migrating a stack
Docker Compose to Kubernetes migration
Migrating Docker stacks to Kubernetes is currently an experimental feature and is not recommended for production workloads.
Before starting the migration, we recommend taking a backup.
Portainer allows you to migrate your Docker Compose workloads to Kubernetes. This feature uses the Kompose tool to convert Docker Compose definitions into Kubernetes resources.
From the stack you want to migrate, select Migrate this stack. In the dialog box that appears, select your Kubernetes environment as the destination for the migration, then complete the fields as described below. Click Migrate.
Namespace
Specify the namespace you wish to migrate to. If the namespace you enter does not exist, a new one will be created during migration.
Convert to Helm chart
Toggle this on to convert your stack to a Helm chart. Note that if migrating to a Helm chart, the preview function will no longer be an option.
Migration between Docker environments
From the stack you want to migrate, select Migrate this stack. Select the destination environment for the stack, and optionally define a new name for the stack. Click Migrate.
Migrating does not relocate the content of any persistent volumes that may be attached to the stack. Acknowledge this warning and confirm the migration by clicking Migrate.
Duplicating a stack
From the stack you want to duplicate, select Migrate this stack. Give the new stack a descriptive name then select the environment the stack should duplicate to. Click Duplicate.
Rename a stack
From the stack you want to rename, select Migrate this stack. Give the stack a new descriptive name and select the environment that the stack is currently on. Click Rename.
Renaming the stack creates a new stack instance and does not transfer the content of any persistent volumes that may be attached to the stack. Acknowledge this warning and confirm the migration by clicking Rename.
