Docker compose as a systemd unit

Create file /etc/systemd/system/docker-compose@.service. SystemD calling binaries using an absolute path. In my case is prefixed by /usr/local/bin, you should use paths specific for your environment.

NOTE: Guide to net/http timeouts

Although not explicitly stated, DNS resolution appears to be taken into consideration as part of the overall http.Client.Timeout setting. If you need to set your own DNS timeout, then it seems https://github.com/miekg/dns is a popular solution.

Additionally, it's important to realise how golang resolves hostnames to IPs (i.e. DNS resolution):
https://golang.org/pkg/net/#hdr-Name_Resolution

When cross-compiling binaries you'll find that CGO is typically disabled in favour of the native Go resolver. You can enforce CGO or native like so:

# ./generate-ios.sh

# flutter build defaults to --release
flutter build ios

# make folder, add .app then zip it and rename it to .ipa
mkdir -p Payload

# FILE: dump.sh
# USAGE: dump.sh [-i interface] [tcpdump-parameters]
# DESCRIPTION: tcpdump on any interface and add the prefix [Interace:xy] in front of the dump data.
# OPTIONS: same as tcpdump
# REQUIREMENTS: tcpdump, sed, ifconfig, kill, awk, grep, posix regex matching
# BUGS:  ---
# FIXED: - In 1.0 The parameter -w would not work without -i parameter as multiple tcpdumps are started.
