1.7. Provision Containers
Provisioning containers
复制链接链接已复制到粘贴板!
All of the prerequisites are now in place for provisioning Red Hat JBoss Fuse containers in the cloud. After joining your local container to the fabric (which enables you to administer the fabric remotely), you can provision a new container in the cloud by entering a single console command.
Join the local container to the fabric
复制链接链接已复制到粘贴板!
To enable administration of the new fabric, first join your local container to the fabric. This makes it possible to administer the fabric by entering console commands in your local container. Invoke the
join command as follows:
JBossFuse:karaf@root> fabric:join -n --zookeeper-password admin 50.19.18.91
Where
50.19.18.91 is the public IP address of the registry container in the cloud (alternatively, you could use the public hostname here). The remote Fabric Server's Zookeeper password must be provided, in order to join the current container to the fabric.
Important
Don't forget to include the
-n option, which ensures that the local container remains a non-managed container (if you forget the -n option, the local container will be re-provisioned automatically and you will lose access to the JClouds and Fabric console commands).
To check that the join has been successful, try listing the containers in the fabric, as follows:
JBossFuse:karaf@root> fabric:container-list
[id] [version] [alive] [profiles] [provision status]
registry 1.0 true fabric, fabric-ensemble-0000-1 success
root* 1.0 true fabricCreate container and deploy profile in one step

If you already know what profiles you want to deploy in the new containers, the most efficient approach is to create the compute instances and specify the profiles all in the same command.
For example, to create two new compute instances as part of the current fabric and to deploy the profiles
mq and fabric into each new container, enter the following console command:
JBossFuse:karaf@root> fabric:container-create-cloud --name aws-ec2
--hardwareId t1.micro --os-family rhel --os-version 6.0
--profile mq --profile fabric mqserver 2
Note how you can deploy multiple profiles, by specifying the
--provider option multiple times. This command produces output like the following:

You can create containers and deploy profiles in separate steps, as follows:
- Create two new Fabric Containers,
mqserver1andmqserver2, as follows:JBossFuse:karaf@root> fabric:container-create-cloud --name aws-ec2 --hardwareId t1.micro --os-family rhel --os-version 6.0 mqserver 2 - Deploy the profiles
mqandfabricinto each of the new Fabric Containers, as follows:JBossFuse:karaf@root> fabric:container-change-profile mqserver1 mq fabric JBossFuse:karaf@root> fabric:container-change-profile mqserver2 mq fabric
Check the provision status

After creating and deploying, you can test the provision status of the new containers using the
fabric:container-list command, as follows:
JBossFuse:karaf@root> fabric:container-list
[id] [version] [alive] [profiles] [provision status]
mqserver1 1.0 true fabric, mq success
mqserver2 1.0 true fabric, mq success
registry 1.0 true fabric, fabric-ensemble-0000-1 success
root* 1.0 true fabric
