sed: can't read .muttrc: No such file or directory about dockerfiles HOT 7 CLOSED

I think the problem is that you're setting the container's HOME environment variable to /home/hostusername/docker-mutt/gmailaccountuser (which is the path on your host), but that path doesn't exist inside the container. I think you want to set that to /home/user instead.

Thank you @tianon ! I modified the command so now it is like this:

docker run -it --rm \
    -e TERM \
    -e [email protected] \
    -e GMAIL_NAME='gmailaccount user' \
    -u "$(id -u):$(id -g)" \
    -e HOME=/home/user \
    -v "$HOME/.signature:/home/user/.signature" \
    -v "$HOME/.muttrc:/home/user/.muttrc.local" \
    -v "$HOME/.mutt/cache:/home/user/.mutt/cache" \
    tianon/mutt-gmail

but then I get the following error:

sed: couldn't open temporary file /home/user/sed8FOvTf: Permission denied

Shouldn't -e HOME=/home/user be a path on the host, so that the volumes set by

    -v "$HOME/.signature:/home/user/.signature" \
    -v "$HOME/.muttrc:/home/user/.muttrc.local" \
    -v "$HOME/.mutt/cache:/home/user/.mutt/cache" \

are set correctly?

from dockerfiles.

Ah, it probably only works on my machine because user inside the container is uid 1000:1000 and matches the user on my host. 😕

I guess the image needs to be updated to make /home/user have wider permissions. 😞

If you don't care which UID/GID the image actually runs as, you could try this:

$ docker run -it --rm \
    -e TERM \
    -e [email protected] \
    -e GMAIL_NAME='gmailaccount user' \
    -v "$HOME/.signature:/home/user/.signature:ro" \
    -v "$HOME/.muttrc:/home/user/.muttrc.local:ro" \
    -v "mutt-gmailaccountuser:/home/user/.mutt/cache" \
    tianon/mutt-gmail

(The important bit there is using a named volume for ~/.mutt/cache instead of a host volume.)

If you don't care about the local cache (which isn't necessary, but makes repeated runs significantly faster), you can even ditch that volume completely.

Thank you a lot for helping with this!

I used the command you mentioned but I still get sed: couldn't open temporary file /home/user/sedeQk8dH: Permission denied.

from dockerfiles.

Ok, let's try simplifying even further to try and narrow this down -- does the following work? (I just tested and it successfully prompts me for a password)

$ docker run -it --rm \
    -e TERM \
    -e [email protected] \
    -e GMAIL_NAME='gmailaccount user' \
    tianon/mutt-gmail

from dockerfiles.

No, it doesn't, I get sed: couldn't open temporary file /home/user/sedKEMqZU: Permission denied

from dockerfiles.

I can't reproduce 😕
