Ggtcf

I want to deploy my local docker project to the google kubernetes engine (or if it's better to google vm engine - I don't know which is more suitable for this project). After deploying on kubernetes engine and exposing the pod on port 80. No wordpress site is shown.

Now I don't know if it's because of my wrong understanding of the cloudbuild.yaml? Can I build multiple containers for my pod and if, how can I connect for instance to the wordpress or mysql container?

I am using the google cloud builder for building the image from my repository (using cloudbuilder.yaml) not Dockerfile.

My docker project consists of a docker-compose.yaml which uses the following services:

1. mariadb:latest


2. nginx (custom build with own Dockerfile)


3. wordpress (custom build with wordpress cli, own Dockerfile)

My docker-compose.yaml (view formatted version here)

version: '3'

services:
 db:
 image: mariadb:latest
 container_name: mysql
 volumes:
 - mariadbdata:/var/lib/mysql
 restart: always
 environment:
 - MYSQL_ROOT_PASSWORD=the_root_pass
 - MYSQL_DATABASE=wordpress
 - MYSQL_USER=wordpress
 - MYSQL_PASSWORD=eveneasier

 my-wordpress:
 container_name: wordpress
 depends_on:
 - db
 build:
 context: .
 dockerfile: build/wordpress/Dockerfile
 restart: always
 volumes:
 - ./wordpress:/var/www/html
 environment:
 - WORDPRESS_DB_HOST=db:3306
 - WORDPRESS_DB_USER=wordpress
 - WORDPRESS_DB_PASSWORD=eveneasier
 - WORDPRESS_DB_NAME=wordpress

 my-nginx:
 container_name: nginx
 depends_on:
 - my-wordpress
 restart: always
 volumes:
 - ./nginx:/etc/nginx/conf.d
 - ./logs/nginx
 - ./wordpress:/var/www/html
 build:
 context: .
 dockerfile: build/nginx/Dockerfile
 ports:
 - "8022:80"
 - "44322:443"
volumes:
 mariadbdata:
 driver: local

Here is my cloudbuild.yaml

steps:
 - name: 'docker/compose:1.19.0'
 args: ['up', '-d']

 - name: 'gcr.io/cloud-builders/docker'
 args: ['tag', 'mariadb', 'gcr.io/$PROJECT_ID/$REPO_NAME:$COMMIT_SHA']

 - name: 'gcr.io/cloud-builders/docker'
 args: ['tag', 'workspace_my-nginx', 'gcr.io/$PROJECT_ID/$REPO_NAME:$COMMIT_SHA']

 - name: 'gcr.io/cloud-builders/docker'
 args: ['tag', 'workspace_my-wordpress', 'gcr.io/$PROJECT_ID/$REPO_NAME:$COMMIT_SHA']

 images: ['gcr.io/$PROJECT_ID/$REPO_NAME:$COMMIT_SHA']

While writing I was wondering if maybe my nginx.conf is the problem, because it uses localhost (127.0.0.1) as host. If so, my other questions still remain.

My nginx.conf:

 server 
 listen 80;
 server_name 127.0.0.1;

 root /var/www/html;
 index index.php;

 access_log /var/log/nginx/access.log;
 error_log /var/log/nginx/error.log;

 location / 
 try_files $uri $uri/ /index.php?$args;
 

 location ~ .php$ 
 try_files $uri =404;
 fastcgi_split_path_info ^(.+.php)(/.+)$;
 fastcgi_pass wordpress:9000;
 fastcgi_index index.php;
 include fastcgi_params;
 fastcgi_param SCRIPT_FILENAME $document_root$fastcgi_script_name;
 fastcgi_param PATH_INFO $fastcgi_path_info;
