Creating the Injector Controller

To create the injector controller, we’ll run a script that creates a namespace, generates certificates, and then installs the injector deployment.

From the base repository directory, change into the injector directory:

cd 2_create_injector

Next, run the create.sh script:

./create.sh

Output should look similar to:

namespace/appmesh-inject created
creating certs in tmpdir /var/folders/02/qfw6pbm501xbw4scnk20w80h0_xvht/T/tmp.LFO95khQ

If you’re seeing the above output, the injector controller has been installed correctly.
