### Clone frappe_docker and switch directory
```shell
git clone https://github.com/frappe/frappe_docker
cd frappe_docker
```
### Load custom apps through json
`apps.json` needs to be passed in as build arg environment variable.
```shell
export APPS_JSON='[
{
"url": "https://github.com/frappe/payments",
"branch": "develop"
},
{
"url": "https://github.com/frappe/erpnext",
"branch": "version-14"
},
{
"url": "https://user:password@git.example.com/project/repository.git",
"branch": "main"
}
]'
```
Note:
- `url` needs to be http(s) git url with token/auth in case of private repo.
### Build Image
```shell
buildah build \
--build-arg=FRAPPE_PATH=https://github.com/frappe/frappe \
--build-arg=FRAPPE_BRANCH=version-14 \
--build-arg=PYTHON_VERSION=3.10.5 \
--build-arg=NODE_VERSION=16.18.0 \
--build-arg=APPS_JSON=$APPS_JSON \
--tag=ghcr.io/user/repo/custom:1.0.0 \
--file=images/custom/Containerfile .
```
Note:
- Use `docker` instead of `buildah` as per your setup.
- Make sure `APPS_JSON` variable has correct JSON.
- Make sure the `--tag` is valid image name that will be pushed to registry.
- Change `--build-arg` as per version of Python, NodeJS, Frappe Framework repo and branch
### Push image to use in yaml files
Login to `docker` or `buildah`
```shell
buildah login
```
Push image
```shell
buildah push ghcr.io/user/repo/custom:1.0.0
```
### Use Kaniko
Following executor args are required. Example runs locally in docker container.
You can run it part of CI/CD or part of your cluster.
```shell
podman run --rm -it \
-v "$HOME"/.docker/config.json:/kaniko/.docker/config.json \
gcr.io/kaniko-project/executor:latest \
--dockerfile=images/custom/Containerfile \
--context=git://github.com/frappe/frappe_docker \
--build-arg=FRAPPE_PATH=https://github.com/frappe/frappe \
--build-arg=FRAPPE_BRANCH=version-14 \
--build-arg=PYTHON_VERSION=3.10.5 \
--build-arg=NODE_VERSION=16.18.0 \
--build-arg=APPS_JSON=$APPS_JSON \
--destination=ghcr.io/user/repo/custom:1.0.0
```
More about [kaniko](https://github.com/GoogleContainerTools/kaniko)
### Use Images
Make sure image name is correct to be pushed to registry. After the images are pushed, you can pull them to servers to be deployed. If the registry is private, additional auth is needed.

## Environment Variables
All of the commands are directly passed to container as per type of service. Only environment variables used in image are for `nginx-entrypoint.sh` command. They are as follows:
- `BACKEND`: Set to `{host}:{port}`, defaults to `0.0.0.0:8000`
- `SOCKETIO`: Set to `{host}:{port}`, defaults to `0.0.0.0:9000`
- `UPSTREAM_REAL_IP_ADDRESS`: Set Nginx config for [ngx_http_realip_module#set_real_ip_from](http://nginx.org/en/docs/http/ngx_http_realip_module.html#set_real_ip_from), defaults to `127.0.0.1`
- `UPSTREAM_REAL_IP_HEADER`: Set Nginx config for [ngx_http_realip_module#real_ip_header](http://nginx.org/en/docs/http/ngx_http_realip_module.html#real_ip_header), defaults to `X-Forwarded-For`
- `UPSTREAM_REAL_IP_RECURSIVE`: Set Nginx config for [ngx_http_realip_module#real_ip_recursive](http://nginx.org/en/docs/http/ngx_http_realip_module.html#real_ip_recursive) Set defaults to `off`
- `FRAPPE_SITE_NAME_HEADER`: Set proxy header `X-Frappe-Site-Name` and serve site named in the header, defaults to `$host`, i.e. find site name from host header. More details [below](#frappe_site_name_header)
- `PROXY_READ_TIMEOUT`: Upstream gunicorn service timeout, defaults to `120`
- `CLIENT_MAX_BODY_SIZE`: Max body size for uploads, defaults to `50m`
To bypass `nginx-entrypoint.sh`, mount desired `/etc/nginx/conf.d/default.conf` and run `nginx -g 'daemon off;'` as container command.
## Configuration
We use environment variables to configure our setup. docker-compose uses variables from `.env` file. To get started, copy `example.env` to `.env`.
### `FRAPPE_VERSION`
Frappe framework release. You can find all releases [here](https://github.com/frappe/frappe/releases).
### `DB_PASSWORD`
Password for MariaDB (or Postgres) database.
### `DB_HOST`
Hostname for MariaDB (or Postgres) database. Set only if external service for database is used.
### `DB_PORT`
Port for MariaDB (3306) or Postgres (5432) database. Set only if external service for database is used.
### `REDIS_CACHE`
Hostname for redis server to store cache. Set only if external service for redis is used.
### `REDIS_QUEUE`
Hostname for redis server to store queue data. Set only if external service for redis is used.
### `REDIS_SOCKETIO`
Hostname for redis server to store socketio data. Set only if external service for redis is used.
### `ERPNEXT_VERSION`
ERPNext [release](https://github.com/frappe/frappe/releases). This variable is required if you use ERPNext override.
### `LETSENCRYPT_EMAIL`
Email that used to register https certificate. This one is required only if you use HTTPS override.
### `FRAPPE_SITE_NAME_HEADER`
This environment variable is not required. Default value is `$$host` which resolves site by host. For example, if your host is `example.com`, site's name should be `example.com`, or if host is `127.0.0.1` (local debugging), it should be `127.0.0.1` This variable allows to override described behavior. Let's say you create site named `mysite` and do want to access it by `127.0.0.1` host. Than you would set this variable to `mysite`.
There is other variables not mentioned here. They're somewhat internal and you don't have to worry about them except you want to change main compose file.

@ -37,7 +37,6 @@ We have several [overrides](https://docs.docker.com/compose/extends/):
- `overrides/compose.proxy.yaml`. Adds traefik proxy to setup.
- `overrides/compose.noproxy.yaml`. Publishes `frontend` ports directly without any proxy.
- `overrides/compose.erpnext.yaml`. Replaces all Frappe images with ERPNext ones. ERPNext images are built on top of Frappe ones, so it is safe to replace them.
- `overrides/compose.https.yaml`. Automatically sets up Let's Encrypt certificate and redirects all requests to directed to http, to https.
- `overrides/compose.mariadb.yaml`. Adds `db` service and sets its image to MariaDB.

## Migrate from multi-image setup
All the containers now use same image. Use `frappe/erpnext` instead of `frappe/frappe-worker`, `frappe/frappe-nginx` , `frappe/frappe-socketio` , `frappe/erpnext-worker` and `frappe/erpnext-nginx`.
Now you need to specify command and environment variables for following containers:
### Frontend
For `frontend` service to act as static assets frontend and reverse proxy, you need to pass `nginx-entrypoint.sh` as container `command` and `BACKEND` and `SOCKETIO` environment variables pointing `{host}:{port}` for gunicorn and websocket services. Check [environment variables](environment-variables.md)
Now you only need to mount the `sites` volume at location `/home/frappe/frappe-bench/sites`. No need for `assets` volume and asset population script or steps.
Example change:
```yaml
# ... removed for brevity
frontend:
image: frappe/erpnext:${ERPNEXT_VERSION:?ERPNext version not set}
command:
- nginx-entrypoint.sh
environment:
BACKEND: backend:8000
SOCKETIO: websocket:9000
volumes:
- sites:/home/frappe/frappe-bench/sites
# ... removed for brevity
```
### Websocket
For `websocket` service to act as socketio backend, you need to pass `["node", "/home/frappe/frappe-bench/apps/frappe/socketio.js"]` as container `command`
Example change:
```yaml
# ... removed for brevity
websocket:
image: frappe/erpnext:${ERPNEXT_VERSION:?ERPNext version not set}
command:
- node
- /home/frappe/frappe-bench/apps/frappe/socketio.js
# ... removed for brevity
```
### Configurator
For `configurator` service to act as run once configuration job, you need to pass `["bash", "-c"]` as container `entrypoint` and bash script inline to yaml. There is no `configure.py` in the container now.
Example change:
```yaml
# ... removed for brevity
configurator:
image: frappe/erpnext:${ERPNEXT_VERSION:?ERPNext version not set}
restart: "no"
entrypoint:
- bash
- -c
command:
- >
bench set-config -g db_host $$DB_HOST;
bench set-config -gp db_port $$DB_PORT;
bench set-config -g redis_cache "redis://$$REDIS_CACHE";
bench set-config -g redis_queue "redis://$$REDIS_QUEUE";
bench set-config -g redis_socketio "redis://$$REDIS_SOCKETIO";
bench set-config -gp socketio_port $$SOCKETIO_PORT;
environment:
DB_HOST: db
DB_PORT: "3306"
REDIS_CACHE: redis-cache:6379
REDIS_QUEUE: redis-queue:6379
REDIS_SOCKETIO: redis-socketio:6379
SOCKETIO_PORT: "9000"
# ... removed for brevity
```
### Site Creation
For `create-site` service to act as run once site creation job, you need to pass `["bash", "-c"]` as container `entrypoint` and bash script inline to yaml. Make sure to use `--no-mariadb-socket` as upstream bench is installed in container.
The `WORKDIR` has changed to `/home/frappe/frappe-bench` like `bench` setup we are used to. So the path to find `common_site_config.json` has changed to `sites/common_site_config.json`.
Example change:
```yaml
# ... removed for brevity
create-site:
image: frappe/erpnext:${ERPNEXT_VERSION:?ERPNext version not set}
restart: "no"
entrypoint:
- bash
- -c
command:
- >
wait-for-it -t 120 db:3306;
wait-for-it -t 120 redis-cache:6379;
wait-for-it -t 120 redis-queue:6379;
wait-for-it -t 120 redis-socketio:6379;
export start=`date +%s`;
until [[ -n `grep -hs ^ sites/common_site_config.json | jq -r ".db_host // empty"` ]] && \
[[ -n `grep -hs ^ sites/common_site_config.json | jq -r ".redis_cache // empty"` ]] && \
[[ -n `grep -hs ^ sites/common_site_config.json | jq -r ".redis_queue // empty"` ]];
do
echo "Waiting for sites/common_site_config.json to be created";
sleep 5;
if (( `date +%s`-start > 120 )); then
echo "could not find sites/common_site_config.json with required keys";
exit 1
fi
done;
echo "sites/common_site_config.json found";
bench new-site frontend --no-mariadb-socket --admin-password=admin --db-root-password=admin --install-app payments --install-app erpnext --set-default;
# ... removed for brevity

SOCKETIO: websocket:9000
volumes:
- sites:/home/frappe/frappe-bench/sites
ports:
- "8082:8080"
```
Notes:
- Replace the port with any port of choice e.g. `listen 4200;`
- Change `mysite.localhost` to site name
- Repeat the server blocks for multiple ports and site names to get the effect of port based multi tenancy
- For old images use `proxy_pass http://erpnext-nginx` instead of `proxy_pass http://frontend`
### Step 3
Run the docker container
```shell
docker run --network=<project-name>_default \
-p 8001:8001 \
--volume=/opt/nginx/conf/serve-8001.conf:/etc/nginx/conf.d/default.conf -d nginx
```
Note: Change the volumes, network and ports as needed
With the above example configured site will be accessible on `http://localhost:8001`
- Above setup will expose `site1.local`, `site2.local`, `site3.local` on port `8080`, `8081`, `8082` respectively.
- Change `site1.local` to site name to serve from bench.
- Change the `BACKEND` and `SOCKETIO` environment variables as per your service names.
- Make sure `sites:` volume is available as part of yaml.

- Make the `frappe-mariadb.cnf` read-only for mariadb container to pick it up.
- While using docker machine, port-forward the port 80 of VM to port 80 of host machine
- Name all the sites ending with `.localhost`. and access it via browser locally. e.g. `http://site1.localhost`
