Upgrade Details

Common Steps for All Upgrade Options

In the sections that follow both Cosmovisor and non-Cosmovisor upgrade paths are provided. Prior to detailing specifics steps for these upgrade paths, in this section we cover steps required regardless of upgrade path chosen.

NOTE - The following steps are not required if the auto-download option is enabled for Cosmovisor.

Either download the Akash binary or build it from source. We highly recommend using a pre-complied binary but provide instructions to build from source here in the rare event it would be necessary.

Option 1: Upgrade Using Cosmovisor

The following instructions assume the akash and cosmovisor binaries are already installed and cosmovisor is set up as a systemd service.

The section that follows will detail the install/configuration of Cosmovisor. If additional details are necessary, visit Start a node with Cosmovisorfor instructions on how to install and set up the binaries.

NOTE - Cosmovisor 1.0 is required

Configure Cosmovisor

Note: The following steps are not required if Cosmovisor v1.0 is already installed and configured to your preferred settings.

To install cosmovisor by running the following command:

go install github.com/cosmos/cosmos-sdk/cosmovisor/cmd/cosmovisor@v1.5.0

Check to ensure the installation was successful:

DAEMON_NAME=akash DAEMON_HOME=~/.akash cosmovisor version

Update cosmovisor systemd service file and make sure the environment variables are set to the appropriate values(the following example includes the recommended settings).

  • NOTE - It is preferable if you start your service under a dedicated non-system user other than root.
  • NOTE - DAEMON_SHUTDOWN_GRACE (optional, default none), if set, send interrupt to binary and wait the specified time to allow for cleanup/cache flush to disk before sending the kill signal. The value must be a duration (e.g. 1s).

Cosmovisor can be configured to automatically download upgrade binaries. It is recommended that validators do not use the auto-download option and that the upgrade binary is compiled and placed manually.

If you would like to enable the auto-download option, update the following environment variable in the systemd configuration file:

Environment="DAEMON_ALLOW_DOWNLOAD_BINARIES=true"

Cosmovisor will automatically create a backup of the data directory at the time of the upgrade and before the migration.

If you would like to disable the auto-backup, update the following environment variable in the systemd configuration file:

Environment="UNSAFE_SKIP_BACKUP=true"

Move the file to the systemd directory:

sudo mv cosmovisor.service /etc/systemd/system/akash.service

Restart cosmovisor to ensure the environment variables have been updated:

systemctl daemon-reload
systemctl start akash
systemctl enable akash

Check the status of the cosmovisor service:

sudo systemctl status cosmovisor

Enable cosmovisor to start automatically when the machine reboots:

sudo systemctl enable cosmovisor.service

Prepare Upgrade Binary

Skip this section if you have enabled DAEMON_ALLOW_DOWNLOAD_BINARIES cosmovisor parameter. It will automatically create the correct path and download the binary based on the plan info from the govt proposal.

Create the folder for the upgrade (v0.28.0) - cloned in this step - and copy the akash binary into the folder.

This next step assumes that the akash binary was built from source and stored in the current (i.e., akash) directory:

mkdir -p $HOME/.akash/cosmovisor/upgrades/v0.28.0/bin
cp ./.cache/bin $HOME/.akash/cosmovisor/upgrades/v0.28.0/bin

At the proposed block height, cosmovisor will automatically stop the current binary (v0.26.X), set the upgrade binary as the new current binary (v0.28.0), and then restart the node.\

Option 2: Upgrade Without Cosmovisor

Using Cosmovisor to perform the upgrade is not mandatory.

Node operators also have the option to manually update the akash binary at the time of the upgrade. Doing it before the upgrade height will stop the node.

When the chain halts at the proposed upgrade height, stop the current process running akash.

Either download the Akash binary or build from source - completed in this step - and ensure the akash binary has been updated:

akash version

Update configuration with

akash init

Restart the process running akash.

Appendix

Build Binary From Sources

Prerequisites

NOTE - we highly recommend downloading a complied Akash binary over building the binary from source

Direnv is required to compile sources. Check here for details on how to install and hook to your shell

if using direnv first time (or cloning sources on to a new host) you should see following message after entering source dir:

Terminal window
direnv: error .envrc is blocked. Run `direnv allow` to approve its content

if no such message, most like direnv is not hooked to the shell

Build
Terminal window
git clone --depth 1 --branch v0.28.2 https://github.com/akash-network/node
cd node
direnv allow
make release

After build artefacts are located in dist directory

Mainnet8 Provider Upgrade Procedure

Overview

This is a comprehensive guide that covers the steps necessary to upgrade from Mainnet5 to Mainnet6 of Akash Network and Akash Provider components in a Kubernetes cluster.

IMPORTANT

This procedure does not apply to Praetor providers!

Praetor providers should wait for further upgrade instructions from Praetor team!

Provider Components to be Upgraded

  • provider-services is the main binary of the akash-provider, akash-hostname-operator, akash-inventory-operator, and akash-ip-operator helm charts
  • akash is the main binary of the akash-node helm chart

Mainnet6 Versions (Pre-Upgrade)

  • provider-services: 0.4.7
  • node: 0.26.0

Mainnet8 Versions (Post-Upgrade)

  • provider-services: 0.4.8
  • node: 0.28.2

Upgrade Procedure

IMPORTANT! Seek help if you encounter an issue at any step or have doubts! Please seek the support in the #providers Akash Network Devs Discord room here.

STEP 1 - Scale down to 0 replicas the akash-provider

This step is crucial to prevent unexpected behavior during the upgrade.

NOTE: The Akash Deployments will continue to run as usual while akash-provider service is stopped. The only impact is that users won’t be able to perform lease-<shell|events|logs> against their deployments nor deploy/update or terminate them.

kubectl -n akash-services scale statefulsets akash-provider --replicas=0

STEP 2 - Upgrade the Helm Charts

Follow these steps to upgrade various Helm charts. Make sure you’ve backed up your existing Helm chart configurations.

Helm charts to be upgraded are: akash-node (aka RPC node), akash-provider, akash-hostname-operator, akash-inventory-operator, and akash-ip-operator.

2.1. Upgrade the Repo
helm repo update akash

Verify you can see the correct chart/app versions:

# helm search repo akash
NAME CHART VERSION APP VERSION DESCRIPTION
akash/akash-hostname-operator 8.0.0 0.4.8 An operator to map Ingress objects to Akash dep...
akash/akash-inventory-operator 8.0.0 0.4.8 An operator required for persistent storage (op...
akash/akash-ip-operator 8.0.0 0.4.8 An operator required for ip marketplace (optional)
akash/akash-node 8.0.0 0.28.2 Installs an Akash RPC node (required)
akash/provider 8.0.0 0.4.8 Installs an Akash provider (required)
2.2. akash-node Chart

Take the current akash-node chart values:

helm -n akash-services get values akash-node | grep -v '^USER-SUPPLIED VALUES' > akash-node-values.yml

Upgrade your akash-node chart:

helm upgrade akash-node akash/akash-node -n akash-services -f akash-node-values.yml
2.3 akash-provider Chart

Take the current akash-provider chart values:

helm -n akash-services get values akash-provider | grep -v '^USER-SUPPLIED VALUES' > provider.yaml
helm upgrade akash-provider akash/provider -n akash-services -f provider.yaml

IMPORTANT: Make sure your provider is using the latest bid price script! Here is the guide that tells you how you can set it for your akash-provider chart. /docs/providers/build-a-cloud-provider/akash-cloud-provider-build-with-helm-charts/#step-8---provider-bid-customization

2.4 akash-hostname-operator Chart
helm upgrade akash-hostname-operator akash/akash-hostname-operator -n akash-services
2.5 akash-inventory-operator Chart

Skip this section if your provider does not provide persistent storage.

Note: This is not a typo, we are installing the inventory-operator without the akash- prefix.

helm upgrade inventory-operator akash/akash-inventory-operator -n akash-services
2.6 akash-ip-operator Chart

Skip this section if your provider does not provide IP leasing.

Take the current akash-ip-operator chart values:

helm -n akash-services get values akash-ip-operator | grep -v '^USER-SUPPLIED VALUES' > akash-ip-operator-values.yml
helm upgrade akash-ip-operator akash/akash-ip-operator -n akash-services -f akash-ip-operator-values.yml

STEP 3 - Verify the Charts Have Been Upgraded

Perform these checks to ensure the upgrade was successful.


Run this command to check the pods and their versions within the akash-services namespace:

kubectl -n akash-services get pods -o custom-columns='NAME:.metadata.name,IMAGE:.spec.containers[*].image'

The charts upgrade went well, if you are seeing these images and versions:

  • provider and operator image is: ghcr.io/akash-network/provider:0.4.8
  • node image is: ghcr.io/akash-network/node:0.28.2

Example Result:

# kubectl -n akash-services get pods -o custom-columns='NAME:.metadata.name,IMAGE:.spec.containers[*].image'
NAME IMAGE
akash-hostname-operator-86d4596d6c-pwbt8 ghcr.io/akash-network/provider:0.4.8
akash-inventory-operator-69464fbdff-dxkk5 ghcr.io/akash-network/provider:0.4.8
akash-ip-operator-6f6ddc47f8-498kj ghcr.io/akash-network/provider:0.4.8
akash-node-1-0 ghcr.io/akash-network/node:0.28.2
akash-provider-0 ghcr.io/akash-network/provider:0.4.8

Update your provider-services client

Make sure to update your local provider-services binary (aka the Akash client) if you had it installed.

Verify the version and the location using these two commands:

provider-services version
type -p provider-services

If you get anything below 0.4.8, then get the right binary from this page.
