I am experiencing an issue where I receive the following error when issuing the docker build command:-
curl: (6) Could not resolve host: dl.yarnpkg.com
gpg: no valid OpenPGP data found.
Here is my Dockerbuild file
# Base image
FROM ruby:2.5.0
RUN curl -sL https://deb.nodesource.com/setup_8.x | bash -
RUN curl -fsSL https://dl.yarnpkg.com/debian/pubkey.gpg | apt-key add -
RUN echo "deb https://dl.yarnpkg.com/debian/ stable main" | tee
/etc/apt/sources.list.d/yarn.lisT
RUN apt-get update
RUN apt-get install -qq -y build-essential libpq-dev nodejs yarn
The commands complete successfully when run outside of docker.
In order to resolve the issues I have tried the following
- Adding DNS servers to /etc/docker/daemon.json - same issue
- Uncommenting the DOCKER_OPTS="--dns 8.8.8.8 --dns 8.8.4.4" line in /etc/default/docker - same issue
- Replacing the DNS servers I use locally in /etc/resolv.conf - same issue.
I have tried DNS servers from Google and OpenDNS, as well as multiple ISPs depending on the location im running the command from
Laptop is running Ubuntu 16:04 with Docker version 18.06.0-ce, build 0ffa825 installed.
Using the following also fails
FROM ruby:2.5.0
RUN apt-get update -qq && apt-get install -y build-essential libpq-dev nodejs
causing the following error
W: Failed to fetch http://deb.debian.org/debian/dists/stretch/InRelease Temporary failure resolving 'deb.debian.org'
W: Failed to fetch http://deb.debian.org/debian/dists/stretch-updates/InRelease Temporary failure resolving 'deb.debian.org'
W: Failed to fetch http://security.debian.org/dists/stretch/updates/InRelease Temporary failure resolving 'security.debian.org'
W: Some index files failed to download. They have been ignored, or old ones used instead.
So I know this isnt just a problem iwth the dl.yarnpkg.com host.
Running the docker build command with the no-cache option makes no difference.
