Cosmovisor Integration - Binaries
cosmovisoris 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.
Installing cosmovisor:
go install cosmossdk.io/tools/cosmovisor/cmd/cosmovisor@latest
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
Manually download the binary and extract it to folder:
Build from source
Ubuntu
git clone https://github.com/pundix/pundix.git
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/
wget https://github.com/pundix/pundix/releases/download/v0.1.3/pundix_0.1.3_Linux_x86_64.tar.gz && tar -xvf pundix_0.1.3_Linux_x86_64.tar.gz -C ~/.pundix/cosmovisor/genesis/
wget https://github.com/pundix/pundix/releases/download/v0.2.1/pundix_0.2.1_Linux_x86_64.tar.gz && tar -xvf pundix_0.2.1_Linux_x86_64.tar.gz -C ~/.pundix/cosmovisor/upgrades/pxv2/
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 foldercp ~/.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
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

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
