Description
This command is typically used in combination with the
fabric:profile-edit command to guarantee atomicity of profile modifications. That is, if multiple edits need to be made to a profile, you can use fabric:container-upgrade to roll out all of the changes in one step.
For example, consider the container,
child1, which is currently assigned to version 1.0 and has the sample profile deployed inside it. If you need to make multiple changes to the sample profile, you can roll out these changes atomically, as follows:
- Create a new version, 1.1, to hold the pending changes, as follows:
karaf@root> fabric:version-create Created version: 1.1 as copy of: 1.0
- Now start editing the new version of the sample profile, remembering to specify
1.1, so that the modifications are applied to version 1.1 ofsample. For example, to add thecamel-quartzfeature to the sample profile, enter the following command:fabric:profile-edit --feature camel-quartz sample 1.1NoteInstead of adding the option1.1to every edit command, you could change the default version to 1.1 by entering the command,fabric:version-set-default 1.1. - When you have finished editing the
sampleprofile and you are ready to let the changes take effect on the container,child1, you can roll out the changes by upgrading thechild1container to version 1.1, as follows:fabric:container-upgrade 1.1 child1
- If you are not happy with the changes you made, you can easily roll back to the old version of the
sampleprofile, using thefabric:container-rollbackcommand, as follows:fabric:container-rollback 1.0 child1
