Docker Buildx on Manjaro

25 Januari 2022 • 1 menit untuk membaca artikel ini

Catatan kecil ketika aku nyobain docker buildx di Laptop dengan OS Manjaro. Aku mencoba build image untuk arm64 dan amd64. Berikut ini ada langkah yang aku tempuh:

Pertama, aku install qemu-user-static ikutin guide ini, ringkasannya begini:

$ uname -m
x86_64

$ docker run --rm -t arm64v8/ubuntu uname -m
standard_init_linux.go:211: exec user process caused "exec format error"

$ docker run --rm --privileged multiarch/qemu-user-static --reset -p yes

$ docker run --rm -t arm64v8/ubuntu uname -m
aarch64

Selanjutnya, aku bikin builder instance

$ docker buildx create --name multiarch --driver docker-container --use

$ docker buildx inspect --bootstrap
# output:
Name:   multiarch
Driver: docker-container

Nodes:
Name:      multiarch0
Endpoint:  unix:///var/run/docker.sock
Status:    running
Platforms: linux/amd64, linux/amd64/v2, linux/amd64/v3, linux/386, linux/arm64, linux/riscv64, linux/ppc64le, linux/s390x, linux/mips64le, linux/mips64

Terakhir, aku coba build image

$ cd projects/personal-blog

# Target arm64
$ docker buildx build --load -t sumarsono/personal-blog:latest-arm64 --platform linux/arm64 .

# Target amd64
$ docker buildx build --load -t sumarsono/personal-blog:latest-amd64 --platform linux/amd64 .

Check hasil build

sumarsono/personal-blog                         latest-amd64                 545e2a6a7c65   24 minutes ago      56.1MB
sumarsono/personal-blog                         latest-arm64                 4c38e55cc0b9   29 minutes ago      54.7MB

Dockerfile yang aku coba:

# build the website
FROM klakegg/hugo:latest-ext AS builder
COPY . /site
WORKDIR /site
RUN hugo --minify

# publish the build result
FROM caddy:2-alpine AS webserver
LABEL maintainer="Sumarsono <[email protected]>"
COPY --from=builder /site/public /usr/share/caddy
