Cosmovisor Integration - Binaries

cosmovisor is a small process manager for Cosmos SDK application binaries that monitors the governance module for incoming chain upgrade proposals. If it sees a proposal that gets approved, cosmovisor can automatically download the new binary, stop the current binary, switch from the old binary to the new one, and finally restart the node with the new binary.

1. Setup Cosmovisor

Installing cosmovisor:

go install

Set up the Cosmovisor environment variables. We recommend setting these in your .profile so it is automatically set in every session.

echo "# Setup Cosmovisor" >> ~/.profile
echo "export DAEMON_NAME=pundixd" >> ~/.profile
echo "export DAEMON_HOME=$HOME/.pundix" >> ~/.profile
source ~/.profile

After this, you must make the necessary folders for cosmosvisor in your DAEMON_HOME directory (~/.pundix) and copy over the current binary.

mkdir -p ~/.pundix/cosmovisor
mkdir -p ~/.pundix/cosmovisor/genesis/bin
mkdir -p ~/.pundix/cosmovisor/upgrades/pxv2

2. Download the Pundix release

Manually download the binary and extract it to folder:

git clone
git checkout release/v0.1.x
make build
cp ./build/bin/pundixd ~/.pundix/cosmovisor/genesis/bin/
git checkout release/v0.2.x
make build
cp ./build/bin/pundixd ~/.pundix/cosmovisor/upgrades/pxv2/bin/

Copying the json upgrade info, you do not need to perform this step if there is no upgrade-info.json file in the ~/.pundix/data/data folder

cp ~/.pundix/data/upgrade-info.json ~/.pundix/cosmovisor/genesis/

To check that you did this correctly, ensure your versions of cosmovisor are the same:

cosmovisor version

3. Start your node

To keep the process always running. If you're on linux, you can do this by creating a service.

sudo tee /etc/systemd/system/pundixd.service > /dev/null <<EOF
Description=Pundix Daemon

ExecStart=/root/go/bin/cosmovisor run start --home=/root/.pundix



Reload, enable and restart the node with daemon service file

sudo -S systemctl daemon-reload
sudo -S systemctl enable pundixd
sudo -S systemctl restart pundixd

You can check the status with

systemctl status pundixd

Accessing logs

journalctl -u pundixd -n 100
