Cloudbreak Deployer configuration is based on environment variables. Cloudbreak Deployer always opens a new bash subprocess without inheriting environment variables. Only the following environment variables are inherited:
To set environment variables relevant for Cloudbreak Deployer, add them to a file called
To see all available environment variables with their default values, run:

Profile file is sourced, so you can use the usual syntax to set configuration values:
export MY_VAR=some_value export OTHER_VAR=another_value
Environment Specific Profiles
Let’s say that you want to use a different version of Cloudbreak for prod and qa profile. Since the
Profile file is sourced, you will have to create two environment specific configurations that can be sourced:
For example, to create and use a prod profile, you need to:
- Create a file called
- Write the environment-specific
Profile.prodto specify Docker image.
- Set the environment variable:
To use the
prod specific profile once, set:
CBD_DEFAULT_PROFILE=prod cbd some_commands
To permanently use the
prod profile, set
export CBD_DEFAULT_PROFILE=prod in your
Using Your Own SSL Certificate
By default Cloudbreak is available only via HTTPS and it generates its own self-signed certificate. For most use cases such as testing or staging instances this is secure enough. However, if you want to use your own trusted certificate, you must manually configure it on the Cloudbreak host by replacing the existing certificate with your own certificate.
- Resolvable domain name for the Cloudbreak hosts' IP addresses
- Generated valid certificate for the domain
- First copy your private key and certificate to the host
- Log in to the host machine via ssh, usually
- Make sure the domain name is resolvable for the host:
- Change the host name of the machine using steps specific for your operating system
- Identify your Cloudbreak location, which usually is
/var/lib/cloudbreak-deployerand navigate there
- Edit your
Profileby adding or replacing
[HOST-NAME]is your actual Cloudbreak host
- Configure TLS details in your
Profileby adding the following line
- Restart Cloudbreak using the
If you want to change SMTP parameters, add them your
The default values of the SMTP parameters are:
export CLOUDBREAK_SMTP_SENDER_USERNAME= export CLOUDBREAK_SMTP_SENDER_PASSWORD= export CLOUDBREAK_SMTP_SENDER_HOST= export CLOUDBREAK_SMTP_SENDER_PORT=25 export CLOUDBREAK_SMTP_SENDER_FROM= export CLOUDBREAK_SMTP_AUTH=true export CLOUDBREAK_SMTP_STARTTLS_ENABLE=true export CLOUDBREAK_SMTP_TYPE=smtp
If your SMTP server uses SMTPS, you must set the protocol in your
If the certificate used by the SMTP server is self-signed or the Java's default trust store doesn't contain it, you can add it to the trust store by copying it to
certs/trusted inside the Cloudbreak Deployer directory, and start (or restart) the Cloudbreak container (with
cbd start). On startup, the Cloudbreak container automatically imports the certificates in that directory to its trust store.
If you would like to replace Cloudbreak's self-signed certificate with your own certificate then copy your certificate and the related private key under cloudbreak-deployment directory:
If the traefik directory does not exsist then create it. After you have coped the cert and private key file, then add the following variable into the Profile file of cbd and restart cbd.
As a best practice we recommend to replace
mydomain.com with the actual domain what you want to use, but make sure that the actual file names and the values in
CBD_TRAEFIK_TLS are identical.
Note: password protected private key files can't be used by Cloudbreak
Access from Custom Domains
Cloudbreak Deployer supports multitenancy and uses UAA as an identity provider. In UAA, multitenancy is managed through identity zones. An identity zone is accessed through a unique subdomain. For example, if the standard UAA responds to https://uaa.10.244.0.34.xip.io, a zone on this UAA can be accessed through a unique subdomain https://testzone1.uaa.10.244.0.34.xip.io.
If you want to use a custom domain for your identity or deployment, add the
UAA_ZONE_DOMAIN line to your
For example, in our hosted deployment, the
identity.sequenceiq.com domain refers to our identity server; therefore, the
UAA_ZONE_DOMAIN variable has to be set to that domain. This variable is necessary for UAA to identify which zone provider should handle the requests that arrive to that domain.
Cloudbreak uses Consul for DNS resolution. All Cloudbreak-related services are registered as someservice.service.consul.
Consul’s built-in DNS server is able to fall back on another DNS server.
This option is called
-recursor. Clodbreak Deployer first tries to discover the DNS settings of the host by looking for nameserver entry in the
/etc/resolv.conf file. If it finds one, consul will use it as a recursor. Otherwise, it will use 126.96.36.199 .
For a full list of available consul config options, see Consul documentation.
To pass any additional Consul configuration, define a
DOCKER_CONSUL_OPTIONS in the
SSH Fingerprint Verification
Cloudbreak is able to verify the SSH fingerprints of the provisioned virtual machines. We disable this feature by default for AWS and GCP, because we have experienced issues caused by the fact that Ccoud providers do not always print the SSH fingerprint into the provisioned machines console output. The fingerprint validation feature can be turned on by configuring the
CB_AWS_HOSTKEY_VERIFY and/or the
CB_GCP_HOSTKEY_VERIFY variables in your
Profile. For example:
export CB_AWS_HOSTKEY_VERIFY=true export CB_GCP_HOSTKEY_VERIFY=true
