Docker issue

1. I had experience once in a blue moon and there's nothing way than to stop/start the docker service. Viola!

Issue:
Error response from daemon: cannot stop container: odoo9: Cannot kill container 0a08b9aefcaa2db053330cbd2b80591a81e68e4027cf6183338fc2700dd940bb: connection error: desc = "transport: dial unix /var/run/docker/containerd/docker-containerd.sock: connect: connection refused": unknown

solution:
sudo /etc/init.d/docker stop
sudo /etc/init.d/docker start





2. When I tried to run latest odoo11 and postgres 10 using docker-compose , I knew I perfectly copied from my configuration in odoo 9 setup but when I hit enter. Bang! issue found.
After a few googling for answers, I think there's some problem with volume. I guess. :)

Issue:

psycopg2.OperationalError: FATAL:  password authentication failed for user "odoo"

Solution:

docker volume rm malphi_malphi_odoo-db-data

3. When I installed a new fresh centos environment in vbox. Everything is new, even docker :)
I have this issue everytime I open the virtual box that docker is not running.

Solution:
sudo systemctl start docker
sudo systemctl enable docker

Print output does not reflecting in the log

It took me a couple of days just to figure out this problem. I know its a simple as you think but I'm wondering why can't show the print output in the log.

For many test attempt that I have done, I finally figure it out.

Simple.

environment:
      - PYTHONUNBUFFERED=1

that's it, just add this to docker-compose yml file.
Eureka!

We will talk about NGINX

I have heard this NGINX a long time ago when I got here in my recent job but I don't know what exactly it is. I had a little knowledge that it will manage the proxy and that's it.

When I deployed docker in our SIT environment (my boss give me the opportunity to use my skill in docker). I heard again NGINX in our discussion and I asked this question. "What is exactly is NGINX?" my boss replied. "Boy, it's a good time to learn something new" and so he explains.

We end up with docker deployed in SIT and installed Odoo environment as well but no NGINX.

Today, I learn this technology by watching youtube.

This link from Quentin Stafford-Fraser who explains very clearly about NGINX

Linux command that you don't know first

1. Linux command to print directory structure in the form of a tree

ls -R | grep ":$" | sed -e 's/:$//' -e 's/[^-][^\/]*\//--/g' -e 's/^/   /' -e 's/-/|/'



2. Change folder ownership

chmod -R 777 directory_name



3. Make it runnable

sudo chmod +x filename.bin


4. Renew IP address
sudo dhclient -r

Change the file permissions to be server-writable?

Linux
Once you have the files set up on your Linux box, and assuming you can SSH into the box to access your SimplePie files:

Navigate to the directory above your cache directory.
Type chmod -Rf 755 ./cache.
If that doesn't work, try 775, then 777 in order until you find one that works.

UPDATED: 9 Jan 2018

I have successfully connected my working directory from host(Windows) to server(virtualbox running centos)

1. add shared folder in virtual box settings.

2. mount below folders
sudo mount -t vboxsf repo2 /home/devlynard/odoo9/app/customaddons

3. add command at start up
edit etc/rc.d/rc.local
make it executable

Eureka!
