Dokku installation in vagrant stuck at importing herokuish into docker

[dianseptiana]

I have ubuntu 14.04 fresh install Vagrant VM, and tried to install dokku v0.4.3 using bootstrap.sh. I set up the VM with 1GB memory. The problem is that the installation always stuck at "Importing herokuish into docker". Although it says that it will take about 5 minutes, but i have waited for about 30 minutes and still, the installation doesn't continue. Is it normal?

Importing herokuish into docker (around 5 minutes)

That isn't normal. Can you try using the VM that comes with the dokku repository and see if that works?

[michaelshobbs]

Could be a transient issue with the docker hub or a networking issue on the client. Definitely not normal. Try destroying the vagrant machine (vagrant destroy) and bringing it up again (vagrant up).

[michaelshobbs]

Ah @josegonzalez is on it. I thought this was from our Vagrantfile. My bad.

[josegonzalez]

The bootstrap method should also work but I think thats a transient issue. Just want to make sure our vm works for you as well.

Are you perhaps behind a firewall or a "bad" internet connection? It's a fairly large file that needs to be downloaded/compiled.

[dianseptiana]

Thank you for your answers.

Actually I tried to run this command manually sudo docker build -t gliderlabs/herokuish /var/lib/herokuish, since this code is in deb.mk file. Now i can see logs that display download progress of docker.io/heroku/cedar repository. I don't know the total size of heroku cedar stack repository that need to be downloaded, but it seems the download process is quite slow. I tried to download file from another site just to test the connection, and the speed is fast enough. By the way, where i can find VM you mentioned @josegonzalez?

[josegonzalez]

@dianseptiana the vm is included with the dokku repository. Simply clone this repo and vagrant up in it.

[josegonzalez]

The file is about 500mb, so maybe you are being throttled on connecting to docker.io. Try downloading another large image from there. Are you on a local connection or on a VPS somewhere?

[dianseptiana]

I'm on local connection. I tried to create instance in amazon EC2, and install using bootstrap.sh. The installation completed successfully without any issues. I guess there is connection problem on my network when pull from docker.io.

I also tried the VM that come with dokku repository. When install use this method, it show logs of download process like this:

==> dokku: Start pulling herokuish from gliderlabs/herokuish:latest
==> dokku: docker images | grep gliderlabs/herokuish || docker pull gliderlabs/herokuish:latest
==> dokku: latest: Pulling from gliderlabs/herokuish
==> dokku: b254a22f653a: Pulling fs layer
==> dokku: a0230b138447: Pulling fs layer
==> dokku: 75231f98abec: Pulling fs layer
==> dokku: 59c44b748d4a: Pulling fs layer
==> dokku: cdc795cfce8a: Pulling fs layer
==> dokku: 612682c89906: Pulling fs layer

==> dokku: 75231f98abec: Verifying Checksum
==> dokku: 75231f98abec: Download complete
==> dokku: cdc795cfce8a: Verifying Checksum
==> dokku: cdc795cfce8a: Download complete
==> dokku: 612682c89906: Verifying Checksum
==> dokku: 612682c89906: Download complete
==> dokku: b254a22f653a: Verifying Checksum
==> dokku: b254a22f653a: Download complete
==> dokku: b254a22f653a: Pull complete
==> dokku: a0230b138447: Pull complete
==> dokku: 75231f98abec: Pull complete

so i can be sure that the process actually continues. Meanwhile when install using bootstrap.sh it just display Importing herokuish into docker (around 5 minutes).

Although i tried using VM that come with dokku and it's display download process log, it still slow in my local machine. Then i found this moby/moby#13309, i think it's related because when download smaller layers, the connection speed is fast. But when download the large layer with 448.2 MB size, the connection speed become very slow.

Welp, this is an upstream issue, so not much we can do about it. Closing, but feel free to add more information to the docker issue if you can figure out any more.
