Bare metal alpine installation

[bcordix]

Basic installation script for Alpine linux v3.23.3. I am using this on a bare metal Alpine installation on a Dell Wyse 3040 thin client. Its pretty trivial to combine with keepalived and dnsdist to get a three node cluster that idles under 10w up to about 18w when pushing 1500 qps through the vip.

#!/bin/sh
#Enable alpine community repo if not already
sed -i '/community/s/^[[:blank:]]*#*//' /etc/apk/repositories
grep -Eq "^http.*?community$" /etc/apk/repositories  || setup-apkrepos -c -1

######## Install technitium
dnsDir="/opt/technitium/dns"
dnsConfig="/etc/dns"
dnsTar="$dnsDir/DnsServerPortable.tar.gz"
dnsUrl="https://download.technitium.com/dns/DnsServerPortable.tar.gz"

mkdir -p ${dnsConfig} ${dnsDir}

apk add curl libmsquic icu aspnetcore9-runtime

curl -o $dnsTar --fail $dnsUrl
tar -zxf $dnsTar -C $dnsDir

echo -e "# Generated by Technitium DNS Server Installer\n\nnameserver 127.0.0.1" > /etc/resolv.conf
echo -e "#!/sbin/openrc-run\nname=\$RC_SVCNAME\ndescription=\"Technitium DNS Server\"\nsupervisor=\"supervise-daemon\"\ncommand=\"/usr/bin/dotnet\"\ncommand_args=\"${dnsDir}/DnsServerApp.dll ${dnsConfig}\"\nsupervise_daemon_args=\" -d ${dnsDir}\"" > /etc/init.d/dns
chmod +x /etc/init.d/dns

rc-update add dns
rc-service dns start
rm $dnsTar
