Day 2 operations¶
Apply an update¶
If you have pulled the most recent version of
tezos-on-gke and wish to apply updates, you may do so with a
terraform taint null_resource.push_containers && terraform taint null_resource.apply && terraform plan -out plan.out
terraform apply plan.out
This will rebuild the containers, then do a
kubectl apply to push the most recent changes to your cluster.
The pods will restart after some time. However, you may kill the pods to restart them immediately.
Tezos Protocol update¶
The Terraform variable
protocol takes a list of Tezos protocols. Tezos regularly updates its protocol based on bakers votes.
In case of imminent protocol upgrade, you may update your cluster after changing the protocol to pass both the old and the new protocol:
protocols =[ "006-PsCARTHA", "007-PsDELPH1" ]
Then, apply the changes. Your baker will restart with the right baking and endorsing daemons.
The baker and endorsers daemons are only active when their protocol is running, otherwise they sit idle. So it is safe to run both at the same time.
Remotely ssh into the remote signers¶
For remote connectivity and debugging purposes, ssh port 22 for the on-prem remote signers is being forwarded on port [signer port + 1000].
To connect to the signers, forward port [signer port + 1000] from the
tezos-remote-signer-forwarder locally, then ssh to localhost using your private key associated with the public key injected into the baker during initial setup.
