Sync strategy

unison

your docker-sync.yml

OS

OSX

In the version 0.5.10 of docker-sync, there are checking whether unox is installed via brew or not. But whenever I run docker-sync, it will complaint

     warning  Could not find eugenmayer/dockersync/unox. Trying to install it now.

or after I do

brew reinstall unox

now it complaint

     warning  You installed unison-fsmonitor (unox) the old legacy way (i.e. not using brew). We need to fix that.

When I check the history, I saw this commit:
https://github.com/EugenMayer/docker-sync/commit/cbf2758567e834b5e188f0ba5974e0a973ce10ab

What bugging me is that brew checking should only affect mac user, so the checking condition should be

@available = Environment.mac? && (defined?(Bundler) ? Bundler.clean_system(cmd) : system(cmd))

I try this in my macbook and now docker-sync can run.

I'll add new pull request for this.

I think we are / will play bug ping pong for sure right now, that is one of the issues

On OSX, this just causes an endless loop.

I've downgraded to 0.5.9 for now.

[EugenMayer]

@cybrox what is "this" - this PR or vaniall 0.5.10?

[cybrox]

@EugenMayer Sorry, didn't see that there was a PR linked to the issue already. "This" in my case is vanilla 0.5.10 using unison and docker-machine on OSX

Hi. Got the same behaviour.

I've got the same bug.

[akinobu-suzuki]

I've got the same bug.

[EugenMayer]

we tried to fix it with the 0.5.11-beta version.
Please manually install it and report back if it gets fixed, thanks!

[petrmatulik]

0.5.11-beta is working for me and fixed it. Thanks so much!

[EugenMayer]

@petrmatulik are you running windows or linux?

[petrmatulik]

I'm running on Mac. But after this update, changed files don't sync automatically. After every change, I must run docker-sync sync. Sorry for the late answer.

[exotec]

How do I install the docker-sync beta GIT Version?

[EugenMayer]

@exotec

gem uninstall docker-sync
gem install docker-sync -v 0.5.11-beta3

@petrmatulik please restart your Mac once please (yes i mean that) and try again. If it happens again, please use the boilerplate https://github.com/EugenMayer/docker-sync-boilerplate in the "default" folder and try if it syncs there. If not even the latter works, please open a new issue describing your case. Thanks!

[exotec]

@EugenMayer thanks a lot! the beta installation is now running. I'm very new with docker, can you tell me please why the sync process only works for me with:
$ docker-sync start

my docker-compose.yml:

   $ docker-compose up -d

Creating network "typo3_default" with the default driver

I think this looks good, but my folders only syncs when I now run
$ docker-sync sync

I discovered that unison-fsmonitor symlink is not created on my mac.
I resolved this issue with command:
brew unlink unox && brew link unox
After that symlink was created and 0.5.10-beta1 is working fine

I found related issue here: https://github.com/hnsl/unox/issues/24

[EugenMayer]

@exotec off-topic, please open a new issue and please consult the wiki before you do so - and the boilerplate.
@exotec thank you for the report. Which OS do you have?
@GGolovenko ah that issue again - well yes, AFAIU link is something the user "uses" or not. It's usually done, but not when the target exists, then you have to enforce it. That is what happened for you. I think this all comes due to brew layout changes or an MacOS upgrade where the old symlink is broken but exists. Maybe the error is also missleading by telling

eugenmayer/dockersync/unox is missing. Maybe we should talk about the expected "location - but this is rather hard to termine. Maybe an additional check to check if it is a broken symlink would help .. you are in for a PR for this? :)
