In the output when building, I am getting this message:
[output clipped, log limit 1MiB reached]
from the command
docker build --progress plain .
The current workaround I have is to pipe larger sections of the RUN command in the dockerfile to /dev/null i.e.
RUN \
echo "**** install packages ****" && \
apt-get update && \
apt-get install -y libcairo2-dev libjpeg-turbo8-dev libpng-dev libtool-bin libossp-uuid-dev wget maven default-jdk > /dev/null
Was on WSL2 docker. The buildx solution somehow didn't work.
But disabling buildkit and piping the output into a file worked for me
So doing this in a bash shell worked for me:
export DOCKER_BUILDKIT=0
docker build --progress plain ./ > logoutput.txt
The other solution is for docker buildx, but some might want a fix for docker build with DOCKER_BUILDKIT=1. The following works for me on ubuntu18.04 and docker version 5:20.10.3~3-0~ubuntu-bionic.
# cat /etc/systemd/system/docker.service.d/env.conf
[Service]
Environment="BUILDKIT_STEP_LOG_MAX_SIZE=1073741824" # you might want to tweak this
Environment="BUILDKIT_STEP_LOG_MAX_SPEED=10240000"
Then:
systemctl daemon-reload
systemctl restart docker.service
With the key link provided by @Luke Deluccia, this is what worked for me.
docker buildx create --use --name larger_log --driver-opt env.BUILDKIT_STEP_LOG_MAX_SIZE=50000000
docker buildx build --progress plain .
This creates a buildx instance, and sets buildx to use the instance when building. This did not clip the logs during the build process.
