Remove dependency on bash #79

jodevsa · 2023-06-25T20:21:27Z

We are currently relying on bash in the agent to update the iptable rules. This isn't really needed and can be done without bash.

iptables-restore was being executed via bash, which was unnecessary. Executing directly is simpler and more reliable. Fixes: jodevsa#79

Bash is also used in two other places:

wireguard-operator/pkg/wireguard/wireguard.go

Line 75 in 8565ade

    
           bashCommand := fmt.Sprintf("mkdir -p /dev/net && if [ ! -c /dev/net/tun ]; then\n    mknod /dev/net/tun c 10 200\nfi && %s %s", wgUserspaceImplementationFallback, iface)

wireguard-operator/internal/it/suite_test.go

Line 100 in 8565ade

    
           bashCommand := fmt.Sprintf("echo \"%s\" | kubectl apply -n %s --context %s -f -", strings.TrimSpace(strings.ReplaceAll(resource, "\"", "\\\"")), namespace, testKindContextName)

…t with native code There is no reason to use bash, or even to call out to the shell for most of what was happening. Replacing it allows for better error handling, clarity and reliability. Fixes: jodevsa#79
