In 100 dagen sterk & fit

Als programmeur krijg ik lang niet de beweging die ik zou moeten hebben. Tel daar bij op dat ik een rugpatiëntje ben door een hernia-operatie op mijn 19e en dan heb je wel het idee dat het tijd wordt om er iets aan te doen. Tijd om weer fit te worden!

Dus ik ga de handen uit de mouwen te steken.

XDebug for PHPUnit in Docker with PHPStorm

[ update ]
Set the IP-address to the following DNS-name: docker.for.mac.localhost (yes, literally)!
Working with the IP-address doesn’t work anymore
[ /update ]

Want to get XDebug working for your PHPUnit tests which run in Docker? Or for behat? Or any other CLI application? Follow me!

Roughly this is what you’ll need to do: Continue reading

Watch files and execute command upon change

Find yourself executing the same command over and over again after applying changes to certain files? Pywatch will be you best friend!

Meet pywatch: a cool little app that watches directories and files. Whenever it finds a file that changed, it executes the command you provided.

TL;DR

As an example; I use this to build a Docker image whenever I save a change to my Dockerfile.

pywatch "docker build . -t pauledenburg/behat" Dockerfile

Or execute tests whenever I make a change to one of the sourcefiles.

commandToExecute='docker exec -i hangman_app_1 behat -c tests/behat/behat.yml'
find ./tests -name "*.php" -o -name "*.feature" \
  | xargs pywatch "$commandToExecute"

This keeps an eye on all *.php and *.feature files under ./tests.

When one of these files changes, it executes $commandToExecute which resolves to executing behat in a Docker container.

Install

Download the pywatch app from github: https://github.com/cmheisel/pywatch.

Then unzip and install with python.

unzip pywatch-master.zip
cd pywatch-master
sudo python setup.py install

Advanced usage

Nice one: run tests when files change and create a Mac notifier whenever the tests fail.

This way you can keep the tests running in the background and you’ll be notified whenever a test failed.

find src tests -name "*.php" -o -name "*.feature" \
  | xargs pywatch "./dev test phpunit" \
  | grep "([0-9]* failed)" \
  | sed -e 's/.*(\([0-9]* failed\)).*/\1/' \
  | while read failure; 
    do 
      terminal-notifier -message "Test output: $failure" -title "Tests Failed!"
    done

 

 

Gitlab CI upload artifact fails: too large

Today I wanted to add a package-job to my Gitlab CI as instructed in this nice Gitlab tutorial.

I created the tar-file but when it came to uploading it failed with Request entity too large.

(...)
ERROR: Uploading artifacts to coordinator... too large archive  id=243 responseStatus=413 Request Entity Too Large status=413 Request Entity Too Large token=JYszbA9F
FATAL: Too large                                   
ERROR: Job failed: exit status 1

It took me some digging, but this is how I fixed this (note, the Nginx proxy was the one giving me a hard time).

Step 1: Set the maximum artifacts size

In your gitlab, go to Settings > Continuous Integration and Deployment > Maximum artifacts size (MB) and set it to the desired value. The default is 100MB.

Step 2: Set the nginx upload size

In the gitlab.rb file, mine at /etc/gitlab/gitlab.rb, set or uncomment the following line.

nginx['client_max_body_size'] = '250m'

 

 

And reconfigure gitlab to get this to work.

gitlab-ctl reconfigure

Step 3: (optional) update your proxy(!)

I run gitlab on docker containers. On the server, I run nginx as a proxy to redirect requests for gitlab to these containers.

I failed to update the proxy configuration to allow the POST-ing of data to the containers.

As I use nginx, this is the line I added. For Apache, just google and you’ll find your answer.

client_max_body_size 0;

This will set no limits on clients sending data.

For reference, this is my whole nginx vhost file.

server {
    listen 80;
    server_name git.pauledenburg.com;
    client_max_body_size 0;

    location / {
        proxy_pass http://localhost:8080;
        proxy_set_header Host $host;
        proxy_set_header X-Real-IP $remote_addr;
        proxy_set_header X-Forwarded-For $proxy_add_x_forwarded_for;
        proxy_set_header X-Forwarded-Proto $scheme;
    }
}

Don’t forget to reload nginx.

$ sudo nginx -t
nginx: the configuration file /etc/nginx/nginx.conf syntax is ok
nginx: configuration file /etc/nginx/nginx.conf test is successful

$ sudo service nginx reload

 

Set up NGINX as a proxy for your Docker containers

Recently I’m a fan of serving docker containers over serving Virtual Hosts using a webserver.

In order to use regular domainnames without ports, I set up Nginx to receive the request on the domainname and let it forward the request to the relevant Docker container on the specific port it is running on.

Example

Imagine I have a Docker webserver-container hosting my app. It runs on my server exposing port 8080. I use the URL app.pauledenburg.com.

I don’t want people to use http://app.pauledenburg.com:8080 but just the URL without the port 

http://app.pauledenburg.com

 .

I use nginx for this:

server {
    listen 80;
    server_name app.pauledenburg.com;

    location / {
        proxy_pass http://localhost:8080;
        proxy_set_header Host $host;
        proxy_set_header X-Real-IP $remote_addr;
        proxy_set_header X-Forwarded-For $proxy_add_x_forwarded_for;
        proxy_set_header X-Forwarded-Proto $scheme;
    }
}

And now add SSL to it 🙂
