Try then to exec in and run a chmod on nf or even just edit it. This can be illustrated by exec in to the following running container:ĭocker run -v /private/var/run/nf:/root/nf -user 0:1 ubuntu tail -f > /dev/null If I mount /etc or /var/run to any random directory on the container and then try and even create a file in the mounted directory, it says the directory isn’t writeable.
#Docker for mac bind mount mac osx
Actual behavior Upgrade to new version of docker on Mac OSX now results in 'The path /etc/localtime is not shared from OS X and is not known to Docker'. This doesn’t seem to just affect one file either. Expected behavior Docker upgrade shouldn't affect already working mount mappings. I’ve even gone as far as to try a user directive to set the UID and GID of the user in the container to be identical to the one with permissions to access the file on the host, to no avail.
#Docker for mac bind mount download
Download the DST3 image by executing following command line on the terminal window: docker pull savageau/dst3. Open a terminal window (macOS and Linux) or Command Prompt (Microsoft Windows) 3. I’ve confirmed that both the UID and GID of the file is the same as the user in the docker container (root). To use the DST3 via Docker follow these simple steps: 1. Then I looked at whether it was the new gRPC Fuse system, but disabling that and even downgrading Docker to 2.3 didn’t work. I considered whether it was MacOS System Integrity Protection (SIP), but I disabled that to ensure it wasn’t the cause. The problem with that is, our VPN client rewrites this file every time it connects or disconnects and does so with the default u+rw permissions. The only solution seems to be to chmod a+rwx (or at the very least g+w) the file, in which case it then works. But even mounting the original file in, still faces permission issues. Now on a mac this is a symlink to /var/run/nf. Problem is, every time the server starts, it throws an error ‘operation not permitted’ because it can’t write to /etc/nf.
This container expects a bind mount from the host’s /etc/nf to the same file in the container in order for it to modify the host’s DNS settings to add itself as the default DNS server on the host. I’m working on a project that uses this: GitHub - mageddo/dns-proxy-server: Solve your DNS hosts from your docker containers, then from your local configuration, then from internet docker image to run a DNS server within a container. I’m currently having an issue that I’ve never encountered before and I’ve hit a complete brick wall regarding it.
