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-quartz
feature to the sample profile, enter the following command:fabric:profile-edit --feature camel-quartz sample 1.1
NoteInstead of adding the option1.1
to 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
sample
profile and you are ready to let the changes take effect on the container,child1
, you can roll out the changes by upgrading thechild1
container 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
sample
profile, using thefabric:container-rollback
command, as follows:fabric:container-rollback 1.0 child1
