Nextcloud in docker with Nginx, Redis and Traefik 🐋

Traefik is used to automatically obtain/renew a TLS certificate and for redirect http to https

Based on an official example

How-to start

Configuration

Replace all change_me with your values

db.env

MYSQL_PASSWORD - nextcloud DB user password

docker-compose.yml

MYSQL_ROOT_PASSWORD - root password for MariaDB container
test: ["CMD", "mysqladmin" ,"ping", "-h", "localhost", "-u", "root", "-pchange_me"] Repeat MYSQL_ROOT_PASSWORD password. This is a database healthcheck. "-pPass" for example
- "traefik.frontend.rule=Host:change_me" Your domain. traefik.frontend.rule=Host:example.com

traefik/config/traefik.toml

domain = "change_me" Yes, domain again
email = "change_me" Your email

Create external network

docker network create traefik

Up

docker-compose up

docker-compose up -d

Storage for data

By default, your data is stored in ./volumes/data

For example, you have a disk for your data and it is mounted to /mnt/storage

Replace with

      - ./volumes/data:/data

      - /mnt/storage:/data

Issues

ERROR: Network traefik declared as external, but could not be found. Please create the network manually using `docker network create traefik` and try again.

Just do what he asks

docker network create traefik

time="2019-08-17T10:46:43Z" level=error msg="Failed to read new account, ACME data conversion is not available : permissions 755 for acme.json are too open, please use 600"

rm -rf traefik/config/acme.json
touch traefik/config/acme.json
chmod 600 traefik/config/acme.json

Move MariaDB database to docker

Backup

sudo -u www-data php /var/www/html/nextcloud/occ maintenance:mode --on
sudo mysqldump --single-transaction -u nextcloud -p nextcloud > ~/nextcloud-dump.sql

Restore

docker exec -it nextcloud-docker_db_1 mysql -h localhost -u root -pPass -e "DROP DATABASE nextcloud"
docker exec -it nextcloud-docker_db_1 mysql -h localhost -u root -pPass -e "CREATE DATABASE nextcloud CHARACTER SET utf8mb4 COLLATE utf8mb4_general_ci"
cat ~/nextcloud-dump.sql | docker exec -i  nextcloud-docker_db_1 mysql -u root -pPass nextcloud
docker-compose down
docker-compose up -d

Other

permission-data.sh?

At the moment, docker-compose does not allow to set permissions on a directory. When volume mounted, the directory inside the container gets root rights. For correct work are needed www-data user rights.

Maintenance nextcloud in docker

docker exec -u www-data -it nextcloud-docker_app_1 php occ maintenance:mode --on

Manual healthcheck Mariadb

docker exec -it nextcloud-docker_db_1 mysqladmin ping -u root -p123
