Whilst helping a colleague dig into some issues he was seeing pulling an IBM WebSphere Liberty image from Docker Hub, I realised that my Ubuntu box was missing a couple of useful utilities, including nslookup and traceroute.
In the latter case, I did have traceroute6 but not the IP v4 equivalent.
Easily fixed ...
apt-get update && apt-get install -y dnsutils traceroute
and now we're good to go: -
which nslookup
/usr/bin/nslookup
nslookup -version
nslookup 9.16.1-Ubuntu
which traceroute
/usr/sbin/traceroute
traceroute --version
Modern traceroute for Linux, version 2.1.0
