Installation

Installation​

Linux/ubuntu​

Required Tools​

KIRA requires the installation of two tools, Cosign and Bash-utils, in order to secure the network and simplify the execution of various tasks.

Cosign​

https://github.com/sigstore/cosign

All KIRA Release Files are signed using sigstore cosign tool. Cosign is a digital signature utility that is used to verify the authenticity and integrity of a file. When a file is signed with a digital signature, it provides a way to verify that the file has not been tampered with, and also to verify the identity of the person or entity who signed the file. It is used in Kira to sign and verify the authenticity of data, such as proprietary tools, binaries and scripts.

Bash-utils​

https://github.com/KiraCore/tools/releases

Bash-utils is a collection of utility functions and aliases for Bash shell scripts developed specifically for KIRA to streamline and simplify the process of executing tasks within the network. It provides various functions for managing environment variables, displaying information, and handling errors.

note

The prerequisite to securely install BU is COSIGN tool that will guarantee the integrity of the files. It MUST be installed and KIRA’s public key added before proceeding.

note

Always source /etc/profile with . /etc/profile when starting a new terminal to use BU.

# assume root permissions
sudo -s && . /etc/profile

# Install essential dependencies
apt-get install -y wget

# Define version of BU you want to install
TOOLS_VERSION="v0.3.46"

# Download BU script
if [ -z "$KIRA_COSIGN_PUB" ] ; then
  echo "ERROR: KIRA_COSIGN_PUB variable is not set. Please refer to cosign installation to add KIRA's public key path as variable."
  exit
fi && \

 wget --user-agent="$UBUNTU_AGENT" "https://github.com/KiraCore/tools/releases/download/$TOOLS_VERSION/${FILE_NAME}.sig" -O ./${FILE_NAME}.sig

# Verify cosign release
cosign verify-blob --key "$KIRA_COSIGN_PUB" --signature "/tmp/${FILE_NAME}.sig" "/tmp/$FILE_NAME" --insecure-ignore-tlog --insecure-ignore-sct

# Install BU
chmod +x ./$FILE_NAME && ./$FILE_NAME bashUtilsSetup && ./etc/profile

# Verify version of BU

Systemd Alternative (requires Python2 Package)​

Systemd is a useful service manager that detects errors or memory overflow in the Sekai node and keeps it keeps it running even after system restarts or power outages.

wget https://raw.githubusercontent.com/gdraheim/docker-systemctl-replacement/master/files/docker/systemctl.py -O /usr/local/bin/systemctl2 && \
chmod +x /usr/local/bin/systemctl2 && \
systemctl2 --version

Others​

apt-get install jq

Sekai Installation​

Login as admin & load environment variables.

sudo -s

Set desired SEKAI release version and binaries repo as env variables within /etc/profile (with bash-utils or manually). Sourcing /etc/profile is necessary.

setGlobEnv SEKAI_VERSION "v0.3.42" && \
setGlobEnv SEKAI_REPO "$HOME/sekai" && \
setGlobEnv NETWORK_NAME "test" && \
setGlobEnv SEKAID_HOME "~/.sekaid-$NETWORK_NAME" && \
loadGlobEnvs

Clone repository and install

rm -fr $SEKAI_REPO && rm -fr $GOBIN/sekaid && mkdir $SEKAI_REPO && cd $SEKAI_REPO && \
git clone https://github.com/KiraCore/sekai.git -b $SEKAI_VERSION $SEKAI_REPO && \
chmod -R 777 ./scripts && make install && \
echo "SUCCESS installed sekaid $(sekaid version)" || echo "FAILED"

Verify successful installation

sekaid version --long

Alternative Installation Processes​

Using Binaries​

cd /tmp && \
PLATFORM="$(getPlatform)" && \
ARCHITECURE="$(getArch)" && \
BIN_DEST="/usr/local/bin/sekaid" && \
safeWget ./sekaid.deb "https://github.com/KiraCore/sekai/releases/download/$SEKAI_VERSION/sekai-${PLATFORM}-${ARCHITECURE}.deb" \
"$KIRA_COSIGN_PUB" && dpkg-deb -x ./sekaid.deb ./sekaid && cp -fv "sekaid/bin/sekaid" $BIN_DEST && chmod -v 755 $BIN_DEST && \

(testing) Using a Docker Base-image Release​

Latest base-image version

Erase previous instances (Optional)

docker rm -f $(docker ps -a -q) && \
docker image prune -a -f

Load base-image in container

IMG_VERSION="v0.13.14"

BASE_NAME="test" && BASE_IMG="[ghcr.io/kiracore/docker/base-image:](http://ghcr.io/kiracore/docker/kira-base:v0.11.4)$IMG_VERSION" && \
docker run -i -t -d --privileged --net bridge --name $BASE_NAME --hostname test.local $BASE_IMG /bin/bash

Enter container

docker start -i $(timeout 3 docker ps --no-trunc -aqf "name=^${BASE_NAME}$" 2> /dev/null || echo -n "")

Install Sekai

rm -fr $SEKAI_REPO && rm -fr $GOBIN/sekaid && mkdir $SEKAI_REPO && cd $SEKAI_REPO && \
git clone https://github.com/KiraCore/sekai.git -b $SEKAI_VERSION $SEKAI_REPO && \
