How can I remove server header in nginx docker container? - docker

Answer 1

more_set_headers is a part of the headers_more module, so it needs an additional nginx package to work properly. nginx-extras could be installed while building docker image for nginx container:
FROM nginx:1.15.6
RUN apt-get update && apt-get install -y nginx-extras
Hope this helps.

Answer 2

Here a solution that worked for me. I took out the version numbers and stripped down the config with only what is really needed.
Dockerfile
FROM ubuntu
RUN apt-get update
RUN apt-get install -y nginx
RUN apt-get install libnginx-mod-http-headers-more-filter
nginx.conf
server_tokens off; # hides version on 404 or 500 pages
more_clear_headers 'Server'; # removes Server header from response headers
server {
...
}
