Error when deploying with git (dokku) - timeout / broken pipe

I use dokku with digital ocean for a while now without any problem

I have a problem now when deploying to dokku leveraging the following command:

git remote add dokku dokku@some-ip:myapp
git push dokku develop:master

I have the following problem:

Counting objects: 528, done.
Delta compression using up to 4 threads.
Compressing objects: 100% (509/509), done.
packet_write_wait: Connection to some-ip port 22: Broken pipe
fatal: The remote end hung up unexpectedly
error: failed to push some refs to 'dokku@some-ip:myapp'

I try

  • set ServerAliveInterval for the ssh client
  • git config http.postBuffer 209715200 / git config ssh.postBuffer 209715200

but it doesn't work. I think it's because the size of the content to push is a bit high...

Thanks for your help!

Update

After set the postBuffer option to the value 209715200, I got the following error:

Counting objects: 528, done.
Delta compression using up to 4 threads.
Compressing objects: 100% (353/353), done.
Timeout, server some-ip not responding.38.00 KiB/s   
fatal: The remote end hung up unexpectedly
error: failed to push some refs to 'dokku@some-ip:myapp'

The last progress hint I have before the upload hangs is:

Writing objects:  87% (466/531), 33.85 MiB | 120.00 KiB/s
dokku ssh git

This generally occurs when the server runs out of memory. You can either add more ram to your server or setup swap space. The follow script will create 2GB of swap space.

sudo install -o root -g root -m 0600 /dev/null /swapfile
dd if=/dev/zero of=/swapfile bs=1k count=2048k
mkswap /swapfile
swapon /swapfile
echo "/swapfile       swap    swap    auto      0       0" | sudo tee -a /etc/fstab
sudo sysctl -w vm.swappiness=10
echo vm.swappiness = 10 | sudo tee -a /etc/sysctl.conf
