Since actions can specify the download source via a url prefix. The prefix may contain some sensitive information that needs to be stored in secrets or variable context, so we need to interpolate the expression value for`uses` firstly.

### ⚠️ Breaking
The `container.network_mode` is a deprecated configuration item. It may be removed after Gitea 1.20 released.
Previously, if the value of `container.network_mode` is `bridge`, it means that `act_runner` will create a new network for job.But `bridge` is easily confused with the bridge network created by Docker by default.
We recommand that using `container.network` to specify the network to which containers created by `act_runner` connect.
### 🆕 container.network
The configuration file of `act_runner` add a new item of `contianer.network`.
In `config.example.yaml`:
```yaml
container:
# Specifies the network to which the container will connect.
# Could be host, bridge or the name of a custom network.
# If it's empty, act_runner will create a network automatically.
network: ""
```
As the comment in the example above says, the purpose of the `container.network` is specifying the network to which containers created by `act_runner` will connect.
`container.network` accepts the following valid values:
- `host`: All of containers (including job containers and service contianers) created by `act_runner` will be connected to the network named `host` which is created automatically by Docker. Containers will share the host’s network stack and all interfaces from the host will be available to these containers.
- `bridge`: It is similar to `host`. All of containers created by `act_runner` will be connected to the network named `bridge` which is created automatically by Docker. All containers connected to the `bridge` (Perhaps there are containers that are not created by `act_runner`) are allowed to communicate with each other, while providing isolation from containers which are not connected to that `bridge` network.
- `<custom_network>`: Please make sure that the `<custom_network>` network already exists firstly (`act_runner` does not detect whether the specified network exists currently. If not exists yet, will return error in the stage of `docker create`). All of containers created by `act_runner` will be connected to `<custom_network>`. After the job is executed, containers are removed and automatically disconnected from the `<custom_network>`.
- empty: `act_runner` will create a new network for each job container and their service containers (if defined in workflow). So each job container and their service containers share a network environment, but are isolated from others container and the Docker host. Of course, these networks created by `act_runner` will be removed at last.
### Others
- If you do not have special needs, we highly recommend that setting `container.network` to empty string (and do not use `container.network_mode` any more). Because the containers created by `act_runner` will connect to the networks that are created by itself. This point will provide better isolation.
- If you set `contianer.network` to empty string or `<custom_network>`, we can be access to service containers by `<service-id>:<port>` in the steps of job. Because we added an alias to the service container when connecting to the network.

#### changes:
- `act` create new networks only if the value of `NeedCreateNetwork` is true, and remove these networks at last. `NeedCreateNetwork` is passed by `act_runner`. 'NeedCreateNetwork' is true only if `container.network` in the configuration file of the `act_runner` is empty.
- In the `docker create` phase, specify the network to which containers will connect. Because, if not specify , container will connect to `bridge` network which is created automatically by Docker.
- If the network is user defined network ( the value of `container.network` is empty or `<custom-network>`. Because, the network created by `act` is also user defined network.), will also specify alias by `--network-alias`. The alias of service is `<service-id>`. So we can be access service container by `<service-id>:<port>` in the steps of job.
- Won't try to `docker network connect ` network after `docker start` any more.
- Because on the one hand, `docker network connect` applies only to user defined networks, if try to `docker network connect host <container-name>` will return error.
- On the other hand, we just specify network in the stage of `docker create`, the same effect can be achieved.
- Won't try to remove containers and networks berfore the stage of `docker start`, because the name of these containers and netwoks won't be repeat.
