docker containers: mariaDB connection issue with nextcloud - docker

I'm the super user at my maschine. There is docker inside my volumne (/volume1/docker). I pulled the latest version of the images and run MariaDB, PhpMyAdmin and NextCloud:
docker run -d --name mariadb --network nextcloud --network-alias db -e MYSQL_ROOT_PASSWORD=r00tp#ss -e MYSQL_USER=nextcloud_rw -e MYSQL_PASSWORD=N3xtCl0ud! -e MYSQL_DATABASE=nextcloud -v /volume1/docker/mariadb:/var/lib/mysql --restart=unless-stopped mariadb:latest
docker run -d --name phpmyadmin --network nextcloud --link mariadb:db -e PMA_ARBITRARY=1 -e PMA_HOST=db -e PMA_USER=nextcloud_rw -e PMA_PASSWORD=N3xtCl0ud! -p 8082:80 --restart=unless-stopped phpmyadmin:latest
docker run -d --name nextcloud --network nextcloud -e MYSQL_HOST=db -e MYSQL_DATABASE=nextcloud -e MYSQL_USER=nextcloud_rw -e MYSQL_PASSWORD=N3xtCl0ud! -v /volume1/docker/nextcloud:/var/www/html -v db:/var/lib/mysql --restart=unless-stopped -p 8080:80 nextcloud:latest
When I open the browser and navigate to http:\\whereNextCloudLives:8080, I see the NextClud background plus the installation form. I enter the user nextcloud and the pw N3xtCl0ud! and get the response "Please check your mysql credentials. Cannot connect to DB".

I just use the IP. There is no domain configured. I've access to the DB with PhpMyAdmin.
Anyone with an idea what is wrong?

Can't access docker container via host browser. Ping is allowed

I created first time some containers via docker-compose in the same new network. After while the env is completed. I see running containers via docker ps. Normally after that i can use containers. But when I tried to access wordpress web page from host via localhost:20000 or :20000. I get ERR_Connection refused. I was expecting info about "Error connecnting to the database".I can ping the containers by docker containers ip from the host. So maybe someone know how to fix that and get access to them.
This happens with this new network - network_1. Other containers like pihole + portainer in default bridge network are accessible from whole host network.
Thank You.

I think
# Database
db:
image: linuxserver/mariadb
volumes:
- db_data:/var/lib/mysql
restart: always
ports:
- 3306:3306
should be
# Database
db:
image: linuxserver/mariadb
volumes:
- db_data:/var/lib/mysql
restart: always
ports:
- 3306:3306

Try another image. I have a lot trouble using linuxserver image after few update. mariadb have official image on docker. Or maybe if you are want to still use linuxserver image, try another mariadb image version.

Docker nginx responds 403 if you are offline

Im running docker with nginx, PHP and MariaDb in my company.
But if my laptop is offline or Im connected with vpn the nginx responds with an 403 error. Docker is starting normally. Do you have any idea why I get the 403 from nginx?
Maybe Its because of the mounted drives?

Edit: I figured out that I cant mount the shared drives. I got an error that the firewall blocks it.

503 Service Temporarily Unavailable nginx/1.13.3 in docker

I am trying to use jwilder/nginx-proxy: alpine in order to start nginx, following is the docker run command and steps:
Step1: docker run -d -p 80:80 -p 443:443 -v /var/run/docker.sock:/tmp/docker.sock:ro --name nginx jwilder/nginx-proxy:alpine
Step2: Opened port 80 in the Security Group of ec2 instance, and trying to connect to ip:80/, but the error is as follows 503 Service Temporarily Unavailable nginx/1.13.3
docker logs says:

jwilder/nginx-proxy doesn't make a lot of sense ran alone. The script behind the magic check other containers environment variables and generate the according rules to reverse proxy from hostname from another container as defined in env var : port defined the same way to the said container & port.
The key here is "hostname from another container". Nginx won't proxy-forward you when you're trying to connect with an IP like you said.
Here's an example from jwielder/nginx's README.md from its github repository
version: '2'
services:
nginx-proxy:
image: jwilder/nginx-proxy
ports:
- "80:80"
volumes:
- /var/run/docker.sock:/tmp/docker.sock:ro
whoami:
image: jwilder/whoami
environment:
- VIRTUAL_HOST=whoami.local <================
Run this, edit your hosts file (something like sudo vim /etc/hosts) add [ec2ip] whoami.local then open your browser for http://whoami.local, that'll work just fine.

Docker: Output shown at http://192.168.99.100:8000/ instead of http://0.0.0.0:8000/

Hi just fount out that the "hello world" is printed out at http://192.168.99.100:8000/ not http://0.0.0.0:8000/ or local:8000.
Although the it's listening at: http://0.0.0.0:8000 (1) . I'm wondering why this is happening. Does anyone know how to fix this? Thanks!

You appear to be using docker-machine, given the IP your ports are exposed to, which means that all the docker-ports are exposed on the results of docker-machine ip. This is because all the containers are running inside of a virtual machine that docker-machine uses (probably in VirtualBox as a VM provider).
If you want to expose this port to 0.0.0.0 or localhost you need make sure you are forwarding the ports in your VirtualBox VM for whatever your docker-machine is. This requires adding the ports under the VM network settings.
