Vous le savez peut-être, Algolia trie les documents lors de l’indexation, et non lors de la recherche. La raison est simple : c’est beaucoup plus rapide lors des recherches si les documents sont déjà triés sur le disque dur ! Cela permet, entre autre, de s’arrêter dès les dix premiers résultats trouvés – plutôt que de récupérer les 4 millions de hits et de les trier en mémoire juste pour remonter le top 10…

The nice thing about the command above is that it shows a unified view of all options and takes into consideration any overrides that may have been applied.
To change the value of an option, ExecStart in this case, do the following:

[ec2-user@ip-10-0-46-113 ~]$ sudo systemctl edit docker

This will create the necessary directory structure under /etc/systemd/system/docker.service.dand open an editor (using the default editor configured for the user) to the override file. Add the section below into the editor:

[Service]
ExecStart=
ExecStart=/usr/bin/docker daemon -H tcp://0.0.0.0:2375 -H unix:///var/run/docker.sock

It was necessary to clear out ExecStart using ExecStart= before setting it to the override value. This is only required for some options and most options in the configuration file would not need to be cleared like this

SYNOPSIS
get-login
[--registry-ids <value> [<value>...]]
[--include-email | --no-include-email]

OPTIONS
--registry-ids (string) A list of AWS account IDs that correspond to
the Amazon ECR registries that you want to log in to.

   --include-email | --no-include-email (boolean) Specify if the '-e' flag
   should  be  included in the 'docker login' command. The '-e' option has
   been deprecated and is removed in docker version 17.06 and  later.  You
   must specify --no-include-email if you're using docker version 17.06 or
   later. The default behavior is to include the '-e' flag in the  'docker
   login' output.

t also adds complexity to the Dockerfile language when there are clear workarounds. Don't push so much config in the parent Dockerfile and leave if for the inheriting images instead. (aka: stop sourcing random images on docker hub :D)

Since docker 17.05 there is also a new way to do multi-stage builds that removes most of the need for this issue (this is a single Dockerfile):

First import the original image

FROM nginx AS source-image

Second step of the build, start with an empty image

FROM scratch

Copy the data from the original image

COPY --from=source-image / /

Re-define all the config

EXPOSE 80
STOPSIGNAL SIGTERM
CMD ["nginx", "-g", "daemon off;"]

EDIT: Forgot to say, the second solution squashes all previous layers. I don't think it's a big deal but it's good to know.
