Utilize multi-stage build to reduce docker image size This reduces the size of the Docker image from ca. 1.2GB down to about 750MB. Also, move unit tests from .travis.yml to Dockerfile. Final production image is not able to run unit tests anymore, as sources are missing from there. 2018-05-28 10:47:56 +00:00			`# Build node feature discovery`
Update builder image to Go 1.13.12 Go versions after 1.13.7 contain fix for CVE-2020-7919 2020-07-10 11:09:41 +00:00			`FROM golang:1.13.12 as builder`
Fixed vulnerabilities in Docker image. - Updated to debian testing (stretch). - Updated to go v1.7. - Added .dockerignore file. 2016-09-20 17:42:00 +00:00
Dockerfile: store build deps in a separate layer Speeds up local builds considerably as the deps are cached (instead of downloading them all on every build) - as long as go.mod and go.sum are not changed. 2019-09-04 15:17:58 +00:00			`# Get (cache) deps in a separate layer`
			`COPY go.mod go.sum /go/node-feature-discovery/`
1. Enabled RDT discovery. 2. Updated the ds to a job for node labelling. 3. Added script to run a job in each node. 4. Updated Readme. 2016-07-12 00:30:49 +00:00
Switch to using go modules Update go version in Docker build image to v1.12. 2019-11-20 13:41:48 +00:00			`WORKDIR /go/node-feature-discovery`

Fix to report the correct version inside container. - Used build args to pass the correct version. 2016-12-09 19:32:39 +00:00			`ARG NFD_VERSION`
Make host mount prefix configurable in Makefile and Dockerfile Introduce a new makefile variable and dockerfile build arg named HOSTMOUNT_PREFIX for changing the prefix used for mounting host directories inside the container. Adds a sed rule in Makefile to generate deployment yamls accordingly. 2020-05-20 16:55:54 +00:00			`ARG HOSTMOUNT_PREFIX`
enable nfd framework on Arm64 platform currently, nfd framework can't be work on Arm64 platform. Fix points: 1, removed rdt on Arm64 platform 2, optimized the code related to multi-arch Change-Id: If605041f6d2243ae2afb3248edbf102083c6dcb4 Signed-off-by: Bin Lu <bin.lu@arm.com> Jira: ENTOS-432 2017-12-20 06:51:56 +00:00

Use Debian strecth-slim as a base for the producion Docker image To cut the image size further, down to about 75MB. We use Debian strecth-slim as the base for the production image as golang docker images use stretch as their base. 2018-05-28 12:41:32 +00:00			`FROM debian:stretch-slim`
