Installing on Raspberry Pi

[grappler]

As a side project it would be fun to try to set up Appflow on a Raspberry Pi.

I am currently using a Raspberry Pi 2 model B.

If you already have a local setup then the following changes need to be made to the host machine e.g. Mac

• Define the IP address for atlantis in /etc/hosts
• Define the IP address and username in ~/.appflow/tenant/required/development/assh.yml

There were a few things that I had to manually do on the Pi to get it further.

• apt-get install etckeeper
• Install Ansible as the debian version does not work https://docs.ansible.com/ansible/intro_installation.html#latest-releases-via-apt-debian
• Install ZSH https://github.com/robbyrussell/oh-my-zsh/wiki/Installing-ZSH
• Create an empty config file for the current and root user sudo touch /home/pi/.zshrc and sudo touch /root/.zshrc
• You also need to mount your development folder http://askubuntu.com/a/504648
• sudo apt-get install haproxy

I am unable to ASSH https://github.com/moul/advanced-ssh-config/issues/226 It could be due to the processor being an ARMv7.

great work;) we need to look in the details then, anyway great for now. Is the web stack already running?

[ivomarino]

are you installing ansible itself also on the pi? Should not be necessary.

[grappler]

are you installing ansible itself also on the pi?

Yes, because the Debian method does not work.

Is the web stack already running?

Not yet, I am only running appflow provision and I can't get past the assh install as it is failing.

[ivomarino]

you can try to skip_tags=assh.

[ivomarino]

I don't understand exactly what you mean with the Debian method.

[grappler]

I don't understand exactly what you mean with the Debian method.

This code does not work... https://github.com/ttssdev/appflow/blob/master/playbooks/roles/common/tasks/ansible.yml#L15

Also holding pagespeed does not work as pagespeed can't be install on a system with an ARMv7 processor https://github.com/ttssdev/appflow/blob/master/playbooks/vars/os/distribution/Debian.yml#L18

[ivomarino]

for testing purpose we could run https://www.raspberrypi.org/downloads/raspbian/ in a VM eventually (no idea if this works, @89luca89 suggestions?).

[grappler]

HAProxy needed to be installed manually. https://github.com/ttssdev/appflow/blob/master/playbooks/roles/lb/tasks/haproxy.yml#L66 There was also a problem with the group ssl-cert not existing. I was able to fix it by changing it to root

There were a few issues with installing PHP as some of the packages were not found and the path for PHP was not correct.

There were a few more errors after that.

Has the provision method been tested with Debian?

[ivomarino]

With Debian Jessie, yes. Raspbian no. We need a Raspbian vm to test I would say, anyway great work till now, can you paste further errors? Thanks

[ivomarino]

Main question is: websites are in place at least?

[grappler]

atlantis/lb works but the websites do not load because I can't finish the setup due to the issues.

[ivomarino]

Paste errors or we can try to debug then via tmate.

[grappler]

These are the errors that I have gotten in the last steps.

[ivomarino]

Ok, we need tmate these days.

[ivomarino]

@grappler any progress on this?

[ivomarino]

closed for now, will be reopened in case we can put hands on a pi.
