### Re-starting a specific Go service for development
|
||||
|
||||
When writing code in an iterative fashion, it is nice to be able to restart a specific service so it will run updated
|
||||
Go code. This decreases the overhead of stopping all services with `docker-compose down` and then re-starting all the
|
||||
services again with 'docker-compose up'.
|
||||
When writing code in an iterative fashion, it is nice to have your change automatically rebuilt. This project uses
|
||||
[github.com/gravityblast/fresh](https://github.com/gravityblast/fresh) to recompile your services that will include most
|
||||
changes.
|
||||
|
||||
Fresh is a command line tool that builds and (re)starts your web application everytime you save a Go or template file.
|
||||
|
||||
The (Fresh configuration file](https://gitlab.com/geeks-accelerator/oss/saas-starter-kit/blob/master/fresh-auto-reload.conf)
|
||||
is located in the project root. By default the following folders are watched by Fresh:
|
||||
- handlers
|
||||
- static
|
||||
- templates
|
||||
|
||||
Any changes to [internal/*](https://gitlab.com/geeks-accelerator/oss/saas-starter-kit/tree/master/internal) or
|
||||
additional project dependencies added to [go.mod](https://gitlab.com/geeks-accelerator/oss/saas-starter-kit/blob/master/go.mod)
|
||||
will require the service to be rebuilt.
|
||||
|
||||
To restart a specific service, first use `docker ps` to see the list of services running.
|
||||
|
||||
```bash
|
||||
$ docker ps
|
||||
CONTAINER ID IMAGE COMMAND NAMES
|
||||
35043164fd0d example-project/web-api:latest "/gosrv" saas-starter-kit_web-api_1
|
||||
d34c8fc27f3b example-project/web-app:latest "/gosrv" saas-starter-kit_web-app_1
|
||||
fd844456243e postgres:11-alpine "docker-entrypoint.s…" saas-starter-kit_postgres_1
|
||||
dda16bfbb8b5 redis:latest "redis-server --appe…" saas-starter-kit_redis_1
|
||||
```
|
||||
|
||||
Then use `docker-compose stop` for a specific service. In the command including the name of service in `docker-compose.yaml` file for the service
|
||||
to shut down. In the example command, we will shut down the web-api service so we can start it again.
|
||||
|
||||
```bash
|
||||
$ docker-compose stop web-app
|
||||
```
|
||||
|
||||
If you are not in the directory for the service you want to restart then navigate to it. We will go to the directory for the
|
||||
web-api.
|
||||
|
||||
```bash
|
||||
$ cd cmd/web-api/
|
||||
```
|
||||
|
||||
Then you can start the service again by running main.go
|
||||
```bash
|
||||
$ go run main.go
|
||||
docker-compose up --build -d web-app
|
||||
```
