# Ergo Docker
|
|
|
|
This folder holds Ergo's Dockerfile and related materials. Ergo
|
|
is published automatically to Docker Hub at
|
|
[ergochat/ergo](https://hub.docker.com/r/ergochat/ergo).
|
|
|
|
The `latest` tag tracks the `stable` branch of Ergo, which contains
|
|
the latest stable release. The `dev` tag tracks the master branch, which
|
|
may by unstable and is not recommended for production.
|
|
|
|
## Quick start
|
|
|
|
The Ergo docker image is designed to work out of the box - it comes with a
|
|
usable default config and will automatically generate self-signed TLS
|
|
certificates. To get a working ircd, all you need to do is run the image and
|
|
expose the ports:
|
|
|
|
```shell
|
|
docker run --name ergo -d -p 6667:6667 -p 6697:6697 ergochat/ergo:tag
|
|
```
|
|
|
|
This will start Ergo and listen on ports 6667 (plain text) and 6697 (TLS).
|
|
The first time Ergo runs it will create a config file with a randomised
|
|
oper password. This is output to stdout, and you can view it with the docker
|
|
logs command:
|
|
|
|
```shell
|
|
# Assuming your container is named `ergo`; use `docker container ls` to
|
|
# find the name if you're not sure.
|
|
docker logs ergo
|
|
```
|
|
|
|
You should see a line similar to:
|
|
|
|
```
|
|
Oper username:password is admin:cnn2tm9TP3GeI4vLaEMS
|
|
```
|
|
|
|
## Persisting data
|
|
|
|
Ergo has a persistent data store, used to keep account details, channel
|
|
registrations, and so on. To persist this data across restarts, you can mount
|
|
a volume at /ircd.
|
|
|
|
For example, to create a new docker volume and then mount it:
|
|
|
|
```shell
|
|
docker volume create ergo-data
|
|
docker run -d -v ergo-data:/ircd -p 6667:6667 -p 6697:6697 ergochat/ergo:tag
|
|
```
|
|
|
|
Or to mount a folder from your host machine:
|
|
|
|
```shell
|
|
mkdir ergo-data
|
|
docker run -d -v $(PWD)/ergo-data:/ircd -p 6667:6667 -p 6697:6697 ergochat/ergo:tag
|
|
```
|
|
|
|
## Customising the config
|
|
|
|
Ergo's config file is stored at /ircd/ircd.yaml. If the file does not
|
|
exist, the default config will be written out. You can copy the config from
|
|
the container, edit it, and then copy it back:
|
|
|
|
```shell
|
|
# Assuming that your container is named `ergo`, as above.
|
|
docker cp ergo:/ircd/ircd.yaml .
|
|
vim ircd.yaml # edit the config to your liking
|
|
docker cp ircd.yaml ergo:/ircd/ircd.yaml
|
|
```
|
|
|
|
You can use the `/rehash` command to make Ergo reload its config, or
|
|
send it the HUP signal:
|
|
|
|
```shell
|
|
docker kill -HUP ergo
|
|
```
|
|
|
|
## Using custom TLS certificates
|
|
|
|
TLS certs will by default be read from /ircd/tls.crt, with a private key
|
|
in /ircd/tls.key. You can customise this path in the ircd.yaml file if
|
|
you wish to mount the certificates from another volume. For information
|
|
on using Let's Encrypt certificates, see
|
|
[this manual entry](https://github.com/ergochat/ergo/blob/master/docs/MANUAL.md#using-valid-tls-certificates).
|
|
|
|
## Using docker-compose
|
|
|
|
This folder contains a sample docker-compose file which can be used
|
|
to start an Ergo instance with ports exposed and data persisted in
|
|
a docker volume. Simply download the file and then bring it up:
|
|
|
|
```shell
|
|
curl -O https://raw.githubusercontent.com/ergochat/ergo/master/distrib/docker/docker-compose.yml
|
|
docker-compose up -d
|
|
```
|
|
|
|
## Building
|
|
|
|
If you wish to manually build the docker image, you need to do so from
|
|
the root of the Ergo repository (not the `distrib/docker` directory):
|
|
|
|
```shell
|
|
docker build .
|
|
```
|
