Akash v0.36.0 Node Upgrade Guide

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 1.5.0 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 cosmossdk.io/tools/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).
Description=Akash with cosmovisor
ExecStart=/root/go/bin/cosmovisor run start

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:


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:


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 (v0.36.0) - 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/v0.36.0/bin
cp ./.cache/bin $HOME/.akash/cosmovisor/upgrades/v0.36.0/bin

At the proposed block height, cosmovisor will automatically stop the current binary (v0.34.X), set the upgrade binary as the new current binary (v0.36.0), 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.


Build Binary From Sources


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


Terminal window
git clone --depth 1 --branch v0.36.0 https://github.com/akash-network/node
cd node
direnv allow
make release

After build artefacts are located in dist directory
