Migrating from cf-release to cf-deployment on AWS
Page last updated:
This topic describes how to migrate your Cloud Foundry deployment
cf-deployment on AWS.
The procedures in this topic are specific to Amazon Web Services (AWS).
For a list of the current prerequisites, see Migration Prerequisites in GitHub.
Perform the following steps:
Set your BOSH Director address, username, and password as environment variables:
$ export BOSH_ENVIRONMENT=YOUR-DIRECTOR-ADDRESS $ export BOSH_CLIENT=YOUR-DIRECTOR-USERNAME $ export BOSH_CLIENT_SECRET=YOUR-DIRECTOR-PASSWORD
Confirm that your BOSH CLI is logged in and working:
$ bosh deployments Using environment 'bosh.example.com' as client 'admin'
Name Release(s) Stemcell(s) Team(s) Cloud Config cf cf/268 bosh-aws-xen-hvm-ubuntu-trusty-go_agent/3421.11 - none cf-diego garden-runc/1.9.0 bosh-aws-xen-hvm-ubuntu-trusty-go_agent/3421.11 - none grootfs/0.21.0 cf-networking/1.2.0 cflinuxfs3/1.138.0 diego/1.23.0 cf/268
Set your Cloud Foundry deployment name as an environment variable:
$ export BOSH_DEPLOYMENT=YOUR-CF-DEPLOYMENT-NAME
If your BOSH Director is configured with a self-signed certificate, perform the following steps to provide that certificate to the BOSH CLI.
- Extract the necessary certificate
from your BOSH Director deployment manifest:
$ bosh interpolate \ --path=/properties/director/ssl/cert PATH-TO-YOUR-BOSH-DIRECTOR-MANIFEST > /tmp/bosh-CA.crt
- Configure the BOSH CLI to use the extracted certificate:
$ export BOSH_CA_CERT=/tmp/bosh-CA.crt
- Extract the necessary certificate from your BOSH Director deployment manifest:
You must build a variables store file from your Cloud Foundry and Diego manifests.
This file contains information that provides environment-specific or sensitive configuration
that the BOSH CLI reads and writes to. The operator uses this file when deploying Cloud Foundry
Perform the following steps to build your variables store file:
- Download your Cloud Foundry and Diego manifests from your existing
$ bosh download-manifest > /tmp/cf-manifest.yml $ bosh download-manifest -d YOUR-DIEGO-DEPLOYMENT-NAME > /tmp/diego-manifest.yml
- Visit the cf-deployment-transition GitHub repository
and use the
extract-vars-store-from-manifests.shscript to generate
To perform a successful migration, you must ensure that your
deploys components at a scale equivalent to your existing Cloud Foundry and Diego deployments.
cf-deployment renames or combines some jobs in
cf-release had a copy of each job for each Availability Zone (AZ),
BOSH was unaware of AZs.
cf-deployment no longer needs this workaround
thanks to first-class support of AZs in BOSH.
This means that several instance groups have been combined,
which has implications for scaling.
For instance, the
diego-cell instance group replaces
cell_z1 and the
cell_z2 instance groups
in your existing Diego deployment.
If you currently have 6 instances each of
you will need 12 instances of
which is configured to use both AZ1 and AZ2.
The BOSH Director will automatically
balance these instances between the AZs.
For a list of all job name changes from
cfr-to-cfd.yml ops file
in the cf-deployment-transition GitHub repository.
This file does not list name changes from the Diego deployment.
However, the only job from the Diego deployment that you must scale is
To scale the components in
cf-deployment, write an ops file.
An ops file is a YAML file that specifies operations to perform on the deployment manifest,
which you provide to the BOSH CLI when deploying Cloud Foundry in the following section.
The following example ops file scales to 12 instances of the
--- - type: replace path: /instance_groups/name=diego-cell/instances value: 12
You must write a cloud config to provide certain properties for
cf-deployment, and upload it to your BOSH Director.
Perform the following steps:
Write a cloud config, drawing its values from your current Cloud Foundry and Diego manifests. Use the following example as the basis for your cloud config:

Keep in mind the following about the above example:
- Unless otherwise noted, all values come from the Cloud Foundry manifest.
- You must include compilation configuration.
- You must include at least the VM types and extensions from the example.
- You must have a network called
- You must configure AZs
- This example assumes that your network setup
allows your Elastic Load Balancers (ELBs) to talk to your deployment
without additional security groups.
If not, you must add an array of
Upload your cloud config to the BOSH Director:
$ bosh update-cloud-config PATH-TO-YOUR-CLOUD-CONFIG
- You must apply the ops file for scaling your components that you created in the previous step.
- You must apply the
cfr-to-cfd.ymlops file. Download this ops file from the cf-deployment-transition GitHub repository. If you are disabling
cf-deploymentfeatures to simplify the transition, you must also apply the appropriate ops files from the transition repository.
deployment-vars.ymlfile you pass with the
--vars-storeflag must be the variables store file you created above.
Delete your Diego deployment by running the following command:
$ bosh -d YOUR-DIEGO-DEPLOYMENT-NAME delete-deployment
This command may take several minutes, because each Diego cell must drain its contents to the new
To delete any unused releases and stemcells from your BOSH Director,
cf-release, run the following command:
$ bosh clean-up --allCreate a pull request or raise an issue on the source for this page in GitHub
