-rw-r--r--. 1 root root 2067 Aug 23 22:17 default.conf
-rw-r--r--. 1 root root   38 Aug 23 19:51 demo-index.html
-rw-r--r--. 1 root root 2939 Aug 23 22:16 Dockerfile

 docker build --no-cache --build-arg \
 API_KEY=eb05ff073455e4bdc5f758290f385988 \
 --build-arg CTRL_HOST=ng-ctlr.lab.f5se.io \
 -t myf5/nginx-plus-sidecar:slim .

• Run docker images to verify the image.

[root@plus1 nginx-plus-image-build]# docker images

myf5/nginx-plus-sidecar   slim                614e06f91830        9 minutes ago       185MB
debian                    stretch-slim        220611111e8c        9 days ago          55.3MB

docker save -o nginx-plus-sidecar-img.tar myf5/nginx-plus-sidecar:slim
docker load -i nginx-plus-sidecar-img.tar
