Deploying Chronicle on Sawtooth


IMPORTANT Chronicle on Sawtooth cannot be deployed unless you have access to BTP's official docker image registry. Once you have acquired the credentials for this registry from BTP you will need to create the target namespace for your deployment and create an image pull secret in that namespace that you can reference later. In this example the namespace is chronicle-namespace and the image pull secret is dockerhub:

kubectl create namespace chronicle-namespace
kubectl config set-context --current --namespace=chronicle-namespace
kubectl create secret docker-registry dockerhub --docker-username=<username> \
--docker-password='<password>' --docker-email=<email>

Selecting Chronicle on Sawtooth in the deployments marketplace takes you to its deployment form. Here you need to give your deployment a name and specify its namespace using the one created above:

Once your deployment has been added, you can view and interact with it as described here.

Warning

Deployment is not instantaneous as under the covers Sextant uses the appropriate helm chart to create your deployment which may involve pulling the appropriate images if these aren't already cached by the Kubernetes cluster.

Sawtooth Services

Once a Chronicle on Sawtooth deployment is running it is possible to expose various Sawtooth features using Kubernetes services. This is covered in depth here.

Deployment Options

Beyond configuring Sawtooth itself these are the deployment options supported by Sextant.

Custom Containers

This option allows you to specify, for example, a custom transaction processor.

Image Pull Secrets

This option allows you to specify any image pull secrets that may be required in order to access images related to your deployment that are hosted in a private repository. These all need to be available in your target namespace.

Advanced Options

Genesis Seed

This option allows you to change the genesis seed on redeployment.

Advanced Deployment Customization

This option provides advanced users with the ability to specify Additional YAML which will override default template options. We recommend that you discuss any proposed customization with us first.
