4. Pourquoi plus légères Human Talks Grenoble octobre 2017 | @_crev_
5. push, pull, run Human Talks Grenoble octobre 2017 | @_crev_
6. container != virtualisation légère Human Talks Grenoble octobre 2017 | @_crev_

8. Examples Human Talks Grenoble octobre 2017 | @_crev_
10. Simple Docker FROM golang WORKDIR /go/src/app COPY . . RUN go-wrapper download RUN go-wrapper install CMD ["go-wrapper", "run"] 737MB Human Talks Grenoble octobre 2017 | @_crev_
11. Pattern Builder FROM golang WORKDIR /go/src/ht_docker_multi_stage COPY . . RUN go-wrapper download CMD ["go", "build", "-v"] FROM gcr.io/distroless/base COPY ht_docker_multi_stage / CMD ["/ht_docker_multi_stage"] Human Talks Grenoble octobre 2017 | @_crev_
12. Pattern Builder (2) build: docker build -t ht_build_and_package-builder -f Dockerfile.build . docker run --rm -v $$PWD:/go/src/ht_docker_multi_stage \ ht_build_and_package-builder 17.5MB Human Talks Grenoble octobre 2017 | @_crev_
13. Multi Stage FROM golang as builder WORKDIR /go/src/ht_docker_multi_stage COPY . . RUN go-wrapper download RUN go-wrapper install FROM gcr.io/distroless/base COPY --from=builder /go/bin/ht_docker_multi_stage / CMD ["/ht_docker_multi_stage"] 17.5MB Human Talks Grenoble octobre 2017 | @_crev_
15. NGinx FROM nginx:1.13-alpine EXPOSE 80 COPY conf/default.conf /etc/nginx/conf.d/default.conf COPY build/ /usr/share/nginx/html Human Talks Grenoble octobre 2017 | @_crev_
16. React build FROM node:8-alpine as dependencies WORKDIR /usr/src/app COPY package.json yarn.lock /usr/src/app/ RUN yarn install FROM node:8-alpine as builder WORKDIR /usr/src/app COPY . . COPY --from=dependencies /usr/src/app/node_modules /usr/src/app/node_modules RUN yarn build FROM nginx:1.13-alpine EXPOSE 80 COPY conf/default.conf /etc/nginx/conf.d/default.conf COPY --from=builder /usr/src/app/build/ /usr/share/nginx/html Human Talks Grenoble octobre 2017 | @_crev_
17. Sass build FROM ruby:2-alpine3.6 as sass RUN apk add --no-cache --virtual build-dep build-base \ && gem install sass --no-doc \ && apk del build-dep && rm -rf /var/cache/apk/* COPY scss /usr/src/app WORKDIR /usr/src/app RUN sass bootstrap.scss > App.css #... FROM node:8-alpine as builder WORKDIR /usr/src/app COPY . . COPY --from=dependencies /usr/src/app/node_modules /usr/src/app/node_modules COPY --from=sass /usr/src/app/App.css /usr/src/app/src/App.css RUN yarn build Human Talks Grenoble octobre 2017 | @_crev_
18. Limites Human Talks Grenoble octobre 2017 | @_crev_
19. Limites Pas de partage de stag Linter pas à jour Docker >= 17.05 Human Talks Grenoble octobre 2017 | @_crev_
20. Limites Pas de partage de stag Comment partager dependencie entre container de dev et container intermédiaire de prod ? Partage de step au travers du cache docker ? Génération des Dockerfile ? Human Talks Grenoble octobre 2017 | @_crev_
21. Limites Linter pas à jour $ docker run --rm -it --privileged -v $PWD:/root/ \ projectatomic/dockerfile-lint dockerfile_lint lint --------ERRORS--------- Line 1: -> FROM ruby:2-alpine3.6 as sass ERROR: Invalid parameters for command.. Reference -> https://docs.docker.com/engine/reference/builder/ Line 12: -> FROM node:8-alpine as dependencies ERROR: Invalid parameters for command.. Reference -> https://docs.docker.com/engine/reference/builder/ Human Talks Grenoble octobre 2017 | @_crev_
22. Limites Docker >= 17.05 Kubernetes < 1.8 docker <= 1.12 Human Talks Grenoble octobre 2017 | @_crev_
23. Avantages Human Talks Grenoble octobre 2017 | @_crev_
24. Avantages Toute la construction présente dans un unique chier Suppression d'outils de build externes (type Makefile ) docker build + docker run , that's all folks Human Talks Grenoble octobre 2017 | @_crev_
25. Thanks Human Talks Grenoble octobre 2017 | @_crev_ | docker run --rm -it squarescale/ybrissaud
