GoCV-compatible OpenCV 3.4 Alpine 3.7 Docker images

What's in build-stage image?

• Alpine 3.7
• FFMPEG 4.0
• Golang 1.10
• OpenCV 3.4.2
• OpenCV 3.4.2 contrib packages required by GoCV

What's in runtime image?

• Alpine 3.7
• Whatever you need there

Purpose

This is a build image for the multi-stage image provisioning as well as runtime image to work with gocv-based binaries.

Example

Sample Docker file you can find here.

Build the runtime image

pushd runtime && docker build -t denismakogon/gocv-alpine:3.4.2-runtime .; popd

Build the build-stage image

pushd build-stage && docker build -t denismakogon/gocv-alpine:3.4.2-buildstage .; popd

Test sample:

pushd example && docker build -t denismakogon/gocv-alpine:test .; popd

docker run --rm -ti denismakogon/gocv-alpine:test

the output should be the following:

gocv version: 0.14.0
opencv lib version: 3.4.2
