### Configuring remote builder for native multi-arch
### Using remote builder for native multi-arch
If you're developing on ARM64 (like Apple Silicon), but you want to deploy on AMD64 (x86 64-bit), you have to use multi-archecture images. By default, MRSK will setup a local buildx configuration that allows for this through QEMU emulation. This can be slow, especially on the first build.
If you're developing on ARM64 (like Apple Silicon), but you want to deploy on AMD64 (x86 64-bit), you can use multi-archecture images. By default, MRSK will setup a local buildx configuration that does this through QEMU emulation. But this can be quite slow, especially on the first build.
If you want to speed up this process by using a remote AMD64 host to natively build the AMD64 part of the image, while natively building the ARM64 part locally, you can do so using builder options like follows:
If you want to speed up this process by using a remote AMD64 host to natively build the AMD64 part of the image, while natively building the ARM64 part locally, you can do so using builder options:
```yaml
builder:
local:
arch: arm64
host: unix:///Users/dhh/.docker/run/docker.sock
host: unix:///Users/<%= `whoami`.strip %>/.docker/run/docker.sock
remote:
arch: amd64
host: ssh://root@192.168.0.1
```
Note: You must have Docker running on the remote host being used as a builder.
Note: You must have Docker running on the remote host being used as a builder. This instance should only be shared for builds using the same registry and credentials.
With that configuration in place, you can setup the local/remote configuration using `mrsk build create`. If you wish to remove the contexts and buildx instances again, you can run `mrsk build remove`. If you had already built using the standard emulation setup, run `mrsk build remove` before doing `mrsk build remote`.
### Using remote builder for single-arch
### Configuring native builder when multi-arch isn't needed
If you're developing on ARM64 (like Apple Silicon), want to deploy on AMD64 (x86 64-bit), but don't need to run the image locally (or on other ARM64 hosts), you can configure a remote builder that just targets AMD64. This is a bit faster than building with multi-arch, as there's nothing to build locally.
If you're developing on the same architecture as the one you're deploying on, you can speed up the build a lot by forgoing a multi-arch image. This can be done by configuring the builder like so:
```yaml
builder:
remote:
arch: amd64
host: ssh://root@192.168.0.1
```
### Using native builder when multi-arch isn't needed
If you're developing on the same architecture as the one you're deploying on, you can speed up the build by forgoing both multi-arch and remote building:
```yaml
builder:
multiarch: false
```
### Configuring build secrets for new images
This is also a good option if you're running MRSK from a CI server that shares architecture with the deployment servers.
Some images need a secret passed in during build time, like a GITHUB_TOKEN to give access to private gem repositories. This can be done by having the secret in ENV, then referencing it like so in the configuration:

### Running a Rails console on the primary host
### Running a Rails console
If you need to interact with the production console for the app, you can use `mrsk app console`, which will start a Rails console session on the primary host. You can start the console on a different host using `mrsk app console --host 192.168.0.2`. Be mindful that this is a live wire! Any changes made to the production database will take effect immeditately.
