We maintain a number of docker images / dockerfiles for third party tools, most of these work pretty similarly by consisting of a singular dockerfile which can be easily build by using docker build.
Nikto is currently the only outlyer requiring a more complex setup and a locally cloned nikto repository.
This should be changed so that the nikto images can be build like the other custom tool images, so that it doesn't need a special pipeline setup but can be build in a matrix build setup.
