Mailu: Docker-compose : ERROR: Invalid interpolation format for "image" option in service ... after using setup utility

[vparres]

Hello,

I just wanted to give a try with the brand new version of Mailu, and i generated a fresh docker-compose configuration trought the setup utility. After backing up my DB, i launched the preconized command in my shell and ... i've got a bunch of error. Googling didn't help me further.

Here's the trace :

vparres@oneill : ~/mailu $> docker-compose pull
docker-compose down --remove-orphans
docker-compose up
ERROR: Invalid interpolation format for "image" option in service "webdav": "${DOCKER_ORG:-mailu}/${DOCKER_PREFIX:-}radicale:${MAILU_VERSION:-1.6}"
ERROR: Invalid interpolation format for "image" option in service "webdav": "${DOCKER_ORG:-mailu}/${DOCKER_PREFIX:-}radicale:${MAILU_VERSION:-1.6}"
ERROR: Invalid interpolation format for "image" option in service "webdav": "${DOCKER_ORG:-mailu}/${DOCKER_PREFIX:-}radicale:${MAILU_VERSION:-1.6}"

Did i made something wrong ?

Thanks !

Hi,

I have toyed around a bit, but couldn’t reproduce your problem. It’d be great if you could provide some more information. What I can think of as being interesting right now would be:

• docker-compose --version
• if possible, your mailu.env (without secret/private parts), otherwise the 3 variables in the image line (DOCKER_ORG, DOCKER_PREFIX, MAILU_VERSION) as set in your mailu.env (just copy-paste a grep here ^_^)
• your docker-compose.yml

I’m really a bit puzzled, the usual mistake that leads to ERROR: Invalid interpolation format is that there’s a $ in some string that was never meant to be a variable, and that needs to be escaped. But the very syntax used in your error works flawlessly here …hence my stab at the compose-version

Hi,

thanks for going all the way — I have just tried with the same docker-compose version that you use, and it fails with the exact same error. What I totally don’t get is why it fails specificially at radicale. Later compose versions (I believe from 1.19 on) check the version: at the top of the file.

Long story short: Could you update to the latest docker-compose, try again, and report back?

Thanks,
-Dario

Note that not all distributions are updating docker or docker-compose anymore. (like fedora is horribly outdated).

In that case it's better to uninstall docker-compose from the package manager and install the latest version from PyPi.

pip3 install docker-compose

Hi,

Sorry for being so long ! I was busy this week, with a lot of work to do.
I upgraded my docker-compose up to 1.21, and ... it worked great ! Mailu is up-to-date, and i had no other issues during upgrade.

I think its interesting to add a note into the doc to notice this.

Thanks for everything and congrats for your great work !

Hello I'm experiencing a similar issue with

docker-compose version 1.8.0, build unknown
docker-py version: 1.9.0
CPython version: 2.7.13
OpenSSL version: OpenSSL 1.1.0j 20 Nov 2018

First I downloaded the 1.6 later master and I got the same error:

docker-compose -p mailu up -d ERROR: Version in "./docker-compose.yml" is unsupported. You might be seeing this error because you're using the wrong Compose file version. Either specify a version of "2" (or "2.0") and place your service definitions under theserviceskey, or omit theversionkey and place your service definitions at the root of the file to use version 1.

I tried to change the version of the file to 2.0 as suggested by the error but then I got:

docker-compose -p mailu up -d ERROR: Invalid interpolation format for "image" option in service "webdav": "${DOCKER_ORG:-mailu}/${DOCKER_PREFIX:-}radicale:${MAILU_VERSION:-master}"

any ideas?

[Nebukadneza]

Hi,

your docker-compose is ~3 years old. I haven’t checked, but it’s likely the syntax isn’t supported yet by your old docker-compose. Please consider upgrading it …

[ghost]

oh thanks,
somehow I saw 18 instead of 1.8.
will update it now.

Hi there,
Unfortunately I'm experiencing the exact same issue on a fresh install of Ubuntu 18.04.02 (latest updates installed).
For Docker and docker-compose I use the versions directly from the docker repository.

docker-compose version 1.17.1
Docker version 18.09.5, build e8ff056

I've tried removing webdav from the docker-compose.yml it than just spits out the same error message from the service "admin".

If you need more info from me I'm happy to help.

[YourBase4]

Hi , i just regged on github to place a comment coz it was not clear to me how to solve this.

looks like mailu dockercompose generates a docker-compose.yml with version 3.6
checking the compat matrix at https://github.com/docker/compose/releases
you need at least docker engine 18.02.0+ . ubuntu has an outdated version.

to fix it on ubuntu 18.4 lts uninstall your docker-compose stuff , logout and login so the snap reference is gone in your shell session , then install docker-compose like https://www.digitalocean.com/community/tutorials/how-to-install-docker-compose-on-ubuntu-18-04

dont forget to chmod +x /usr/local/bin/docker-compose

after that I get
Creating mailu_front_1 ... done
Creating mailu_webdav_1 ... done
Creating mailu_resolver_1 ... done
Creating mailu_redis_1 ... done
Creating mailu_imap_1 ... done
Creating mailu_webmail_1 ... done
Creating mailu_antivirus_1 ... done
Creating mailu_smtp_1 ... done
Creating mailu_antispam_1 ... done
Creating mailu_fetchmail_1 ... done
Creating mailu_admin_1 ... done
docker-mailu@mail2:/mailu$

[ictinc]

Thanks for that link. I installed both Docker and docker-compose from the docker Ubuntu repository, which gave me these errors.
Fortunately after removing docker-compose and installing it through the link you posted solved the problem and made me install Mailu.
Thanks a lot.

[muhlemmer]

Looking at https://github.com/Mailu/Mailu/graphs/traffic this page seems to be one of the most visited in our repository. Yet, we have not updated our documentation / faq to point out:

• docker-compose shipped with ubuntu is too old
• How to get a newer / proper version.

I'm reopening this because Ubuntu is the most popular and beginner friendly distribution. And the stats point out a lot of (new/inexperienced?) users are bitten by this. It is not a friendly welcome.

I would like the documentation, or FAQ, to be more clear around this subject in order to prevent novice users falling for this. Help is welcome.

I have the same issue and I am on Docker version 19.03.6, build 369ce74a3c
