### Getting Started The templates in this repository will help deploy Frappe/ERPNext docker in a production environment. This docker installation takes care of the following: * Setting up the desired version of Frappe/ERPNext. * Setting up all the system requirements: eg. MariaDB, Node, Redis. * [OPTIONAL] Configuring networking for remote access and setting up LetsEncrypt ### Installation Process #### Setting up Pre-requisites This repository requires Docker and Git to be setup on the instance to be used. #### Setup Letsencrypt Nginx Proxy Companion This is an optional first step. This step is only required if you want to have SSL setup on your docker instance. This step also assumes that the DNS is preconfigured since it automatically handles setup and renewal of SSL certificates. For more details, see: https://github.com/evertramos/docker-compose-letsencrypt-nginx-proxy-companion To setup the proxy companion, run the following steps: ```sh cd $HOME git clone https://github.com/evertramos/docker-compose-letsencrypt-nginx-proxy-companion.git cd docker-compose-letsencrypt-nginx-proxy-companion cp .env.sample .env ./start.sh ``` #### Setting up Frappe/ERPNext Docker Clone this repository somewhere in your system: ```sh git clone https://github.com/frappe/frappe_docker.git cd frappe_docker ``` Copy the example docker environment file to `.env`: ``` cp installation/env-example installation/.env ``` Make a directory for sites: ```sh mkdir installation/sites ``` #### Setup Environment Variables Docker allows passing an environment file to aide in setting up containers, which is used by this repository to pass secret and variable data. To get started, copy the existing `env-example` file to `.env` inside the `installation` directory. By default, the file will contain the following variables: - `VERSION=edge` - In this case, `edge` corresponds to `develop`. To setup any other version, you may use the branch name or version specific tags. (eg. version-12, v11.1.15, v11) - `MYSQL_ROOT_PASSWORD=admin` - Bootstraps a MariaDB container with this value set as the root password. If a managed MariaDB instance is to be used, there is no need to set the password here. - `MARIADB_HOST=mariadb` - Sets the hostname to `mariadb`. This is required if the database is managed with the containerized MariaDB instance. - In case of a separately managed database setup, set the value to the database's hostname/IP/domain. - `SITES=site1.domain.com,site2.domain.com` - List of sites that are part of the deployment "bench". Each site is separated by a comma(,). - If LetsEncrypt is being setup, make sure that the DNS for all the site domains are pointing to the current instance. - `LETSENCRYPT_EMAIL=your.email@your.domain.com` - Email for LetsEncrypt expiry notification. This is only required if you are setting up the nginx proxy companion. #### Start Frappe/ERPNext Services To start the Frappe/ERPNext services, run the following command: ```sh docker-compose \ --project-name \ -f installation/docker-compose-common.yml \ -f installation/docker-compose-erpnext.yml \ -f installation/docker-compose-networks.yml \ --project-directory installation up -d ``` Make sure to replace `` with any desired name you wish to set for the project. Note: use `docker-compose-frappe.yml` in case you need bench with just frappe installed. #### Setup New Sites Note: - Wait for the mariadb service to start before trying to create a new site. - If new site creation fails, retry after the mariadb container is up and running. - If you're using a managed database instance, make sure that the database is running before setting up a new site. - Use `.env` file or environment variables instead of passing secrets as command arguments. ```sh # Create ERPNext site docker exec -it \ -e "SITE_NAME=$SITE_NAME" \ -e "DB_ROOT_USER=$DB_ROOT_USER" \ -e "MYSQL_ROOT_PASSWORD=$MYSQL_ROOT_PASSWORD" \ -e "ADMIN_PASSWORD=$ADMIN_PASSWORD" \ -e "INSTALL_ERPNEXT=1" \ _erpnext-python_1 docker-entrypoint.sh new ``` Environment Variables needed: - `SITE_NAME`: name of the new site to create. - `DB_ROOT_USER`: MariaDB Root user. The user that can create databases. - `MYSQL_ROOT_PASSWORD`: In case of mariadb docker container use the one set in `MYSQL_ROOT_PASSWORD` in previous steps. In case of managed database use appropriate password. - `ADMIN_PASSWORD`: set the administrator password for new site. - `INSTALL_ERPNEXT=1`: available only in erpnext-worker and erpnext containers. Installs ERPNext on this new site. - `FORCE=1`: is optional variable which force installs the same site. #### Backup Sites Environment Variables - `SITES` is list of sites separated by (:) colon to migrate. e.g. `SITES=site1.domain.com` or `SITES=site1.domain.com:site2.domain.com` By default all sites in bench will be backed up. - `WITH_FILES` if set to 1, it will backup user uploaded files for the sites. ```sh docker exec -it \ -e "SITES=site1.domain.com:site2.domain.com" \ -e "WITH_FILES=1" \ _erpnext-python_1 docker-entrypoint.sh backup ``` Backup will be available in the `sites` mounted volume. #### Updating and Migrating Sites Switch to the root of the `frappe_docker` directory before running the following commands: ```sh # Update environment variable VERSION nano .env # Pull new images docker-compose \ -f installation/docker-compose-common.yml \ -f installation/docker-compose-erpnext.yml \ pull # Restart containers docker-compose \ --project-name \ -f installation/docker-compose-common.yml \ -f installation/docker-compose-erpnext.yml \ -f installation/docker-compose-networks.yml \ --project-directory installation up -d docker exec -it \ -e "MAINTENANCE_MODE=1" \ _erpnext-python_1 docker-entrypoint.sh migrate ``` ### Troubleshoot 1. Remove containers and volumes, and clear redis cache: This can be used when existing images are upgraded and migration fails. ``` # change to repo root cd $HOME/frappe_docker # Stop all bench containers docker-compose \ --project-name \ -f installation/docker-compose-common.yml \ -f installation/docker-compose-erpnext.yml \ -f installation/docker-compose-networks.yml \ --project-directory installation stop # Remove redis containers docker-compose \ --project-name \ -f installation/docker-compose-common.yml \ -f installation/docker-compose-erpnext.yml \ -f installation/docker-compose-networks.yml \ --project-directory installation rm redis-cache redis-queue redis-socketio # Clean redis volumes docker volume rm \ _redis-cache-vol \ _redis-queue-vol \ _redis-socketio-vol # Restart project docker-compose \ --project-name \ -f installation/docker-compose-common.yml \ -f installation/docker-compose-erpnext.yml \ -f installation/docker-compose-networks.yml \ --project-directory installation up -d ``` 2. Clear redis cache using `docker exec` command: In case of following error during container restarts: ``` frappe-worker-short_1 | Traceback (most recent call last): frappe-worker-short_1 | File "/home/frappe/frappe-bench/commands/worker.py", line 5, in frappe-worker-short_1 | start_worker(queue, False) frappe-worker-short_1 | File "/home/frappe/frappe-bench/apps/frappe/frappe/utils/background_jobs.py", line 147, in start_worker frappe-worker-short_1 | Worker(queues, name=get_worker_name(queue)).work(logging_level = logging_level) frappe-worker-short_1 | File "/home/frappe/frappe-bench/env/lib/python3.7/site-packages/rq/worker.py", line 474, in work frappe-worker-short_1 | self.register_birth() frappe-worker-short_1 | File "/home/frappe/frappe-bench/env/lib/python3.7/site-packages/rq/worker.py", line 261, in register_birth frappe-worker-short_1 | raise ValueError(msg.format(self.name)) frappe-worker-short_1 | ValueError: There exists an active worker named '8dfe5c234085.10.short' already ``` Use commands : ```sh # Clear the cache which is causing problem. docker exec -it _redis-cache_1 redis-cli FLUSHALL docker exec -it _redis-queue_1 redis-cli FLUSHALL docker exec -it _redis-socketio_1 redis-cli FLUSHALL ``` Note: Environment variables from `.env` file located at current working directory will be used.
