## Docker Image
|
||
|
|
|
||
|
|
Included in this repo is a Dockerfile that you can launch harmony node for trying it out. Docker images are available on `harmonyone/harmony`.
|
||
|
|
|
||
|
|
You can build the docker image with the following commands:
|
||
|
|
```bash
|
||
|
|
make docker
|
||
|
|
```
|
||
|
|
|
||
|
|
If your build machine has an ARM-based chip, like Apple silicon (M1), the image is built for `linux/arm64` by default. To build for `x86_64`, apply the --platform arg:
|
||
|
|
|
||
|
|
```bash
|
||
|
|
docker build --platform linux/amd64 -t harmonyone/harmony -f Dockerfile .
|
||
|
|
```
|
||
|
|
|
||
|
|
Before start the docker, dump the default config `harmony.conf` by running:
|
||
|
|
|
||
|
|
for testnet
|
||
|
|
```bash
|
||
|
|
docker run -v $(pwd)/config:/harmony --rm --name harmony harmonyone/harmony harmony config dump --network testnet harmony.conf
|
||
|
|
```
|
||
|
|
for mainnet
|
||
|
|
```bash
|
||
|
|
docker run -v $(pwd)/config:/harmony --rm --name harmony harmonyone/harmony harmony config dump harmony.conf
|
||
|
|
```
|
||
|
|
|
||
|
|
make your customization. `harmony.conf` should be mounted into default `HOME` directory `/harmony` inside the container. Assume `harmony.conf`, `blskeys` and `hmykey` are under `./config` in your current working directory, you can start your docker container with the following command:
|
||
|
|
```bash
|
||
|
|
docker run -v $(pwd)/config:/harmony --rm --name harmony -it harmonyone/harmony
|
||
|
|
```
|
||
|
|
|
||
|
|
If you need to open another shell, just do:
|
||
|
|
```bash
|
||
|
|
docker exec -it harmonyone/harmony /bin/bash
|
||
|
|
```
|
||
|
|
|
||
|
|
We also provide a `docker-compose` file for local testing
|
||
|
|
|
||
|
|
To use the container in kubernetes, you can use a configmap or secret to mount the `harmony.conf` into the container
|
||
|
|
```bash
|
||
|
|
containers:
|
||
|
|
- name: harmony
|
||
|
|
image: harmonyone/harmony
|
||
|
|
ports:
|
||
|
|
- name: p2p
|
||
|
|
containerPort: 9000
|
||
|
|
- name: rpc
|
||
|
|
containerPort: 9500
|
||
|
|
- name: ws
|
||
|
|
containerPort: 9800
|
||
|
|
volumeMounts:
|
||
|
|
- name: config
|
||
|
|
mountPath: /harmony/harmony.conf
|
||
|
|
volumes:
|
||
|
|
- name: config
|
||
|
|
configMap:
|
||
|
|
name: cm-harmony-config
|
||
|
|
|
||
|
|
```
|
||
|
|
|
||
|
|
Your configmap `cm-harmony-config` should look like this:
|
||
|
|
```
|
||
|
|
apiVersion: v1
|
||
|
|
kind: ConfigMap
|
||
|
|
metadata:
|
||
|
|
name: cm-harmony-config
|
||
|
|
data:
|
||
|
|
harmony.conf: |
|
||
|
|
...
|
||
|
|
```
