# Deploying WebApps from the Laconic Registry to Kubernetes
First, ensure you have `laconicd` and the console running via [this tutorial](./laconicd-with-console.md).
## Setup Kubernetes
If merely requesting deployment, access to the Laconic registry is sufficient, but to *process* deployment requests, Kubernetes configuration is also necessary. The configuration format is the same as used by `kubectl`, and should be places in `/etc/config/kube.yml`
## Setup the Deployer
### Set envs
```
$DEPLOYMENT_DNS_SUFFIX
$DEPLOYMENT_RECORD_NAMESPACE
$IMAGE_REGISTRY
$IMAGE_REGISTRY_CREDS
$IMAGE_REGISTRY_USER
```
```
laconic-so --stack webapp-deployer-backend setup-repositories
laconic-so --stack webapp-deployer-backend build-containers
laconic-so --stack webapp-deployer-backend deploy up
```
## Setup Your Account
Writing to the Laconic Registry, in order to create records for applications and deployment requests, requires a user key, and a bond with adequate funds available.
### Install the registry CLI
```
npm config set @cerc-io:registry https://git.vdb.to/api/packages/cerc-io/npm/
npm install -g @cerc-io/laconic-registry-cli
```
Alternatively, use the pre-configured container that was setup alongside `laconicd`
### Get your private key
```
exec into laconicd
```
### config.yml
```
services:
cns:
restEndpoint: http://console.laconic.com:1317
gqlEndpoint: http://console.laconic.com:9473/api
userKey: 3d4789e88508c6230d973ccea283032d3e3948775dbe02f4f0a80dc6c1f7c8d5
# bondId: 3c61577f3c6197ced599e2fc21ccf76f43373004fd29c29f2e560c77f7c4bb6d
chainId: laconic_9000-1
gas: 550000
fees: 200000aphoton
```
### Create a bond
```
laconic cns -c config.yml bond create --type aphoton --quantity 1000000000 --gas 200000 --fees 200000aphoton
```
# Creating Deployments
Deploying an application from the registry requires (and generates)
several records:
1. An `ApplicationRecord` which describes the application itself, including its name, version, and repository.
2. An `ApplicationDeploymentRequest` which references an`ApplicationRecord`, and provides additional information such as the DNS name and configuration.
3. A `DnsRecord`, which contains the FQDN of the deployment. The ownership of this record will be checked against any future deployment or removal requests.
4. An `ApplicationDeploymentRecord` which records the successful processing of the deployment request.
Additionally, since names need to be registered, namespace authorities need to be reserved, for example:
```
$ laconic -c $LACONIC_CONFIG cns authority reserve my-org-name
$ laconic -c $LACONIC_CONFIG cns authority bond set my-org-name 0e9176d854bc3c20528b6361aab632f0b252a0f69717bf035fa68d1ef7647ba7
```
## Application Records
The `ApplicationRecord` should, at a minimum, specify the name of the application (`name`), its version (`app_version`), type (`app_type`), one or more repository URLs (`repository`), and the repository reference (eg, branch, tag, hash, etc.) to use (`repository_ref`).
```
$ cat app.yml
record:
type: ApplicationRecord
version: 0.0.4
name: "@my-org-name/my-test-webapp"
repository:
- "https://github.com/my-org-name/my-test-webapp"
repository_ref: "v0.1.5"
app_version: "0.1.5"
app_type: "webapp"
$ laconic -c $LACONIC_CONFIG cns record publish -f app.yml
bafyreihwvu6ynmk4nfrxg2vdcx2ep3tqry775ksqyehjitj2i4kphhyuky
```
One or more names should be registered for the application, which deployment requests can reference.
```
$ laconic -c $LACONIC_CONFIG cns name set "crn://my-org-name/applications/my-test-webapp" bafyreihwvu6ynmk4nfrxg2vdcx2ep3tqry775ksqyehjitj2i4kphhyuky
$ laconic -c $LACONIC_CONFIG cns name set "crn://my-org-name/applications/my-test-webapp@0.1.5" bafyreihwvu6ynmk4nfrxg2vdcx2ep3tqry775ksqyehjitj2i4kphhyuky
$ laconic -c $LACONIC_CONFIG cns record get --id bafyreihwvu6ynmk4nfrxg2vdcx2ep3tqry775ksqyehjitj2i4kphhyuky
[
{
"id": "bafyreihwvu6ynmk4nfrxg2vdcx2ep3tqry775ksqyehjitj2i4kphhyuky",

],
"repository_ref": "v0.1.5",
"type": "ApplicationRecord",
"version": "0.0.4"
}
}
]
```
## Application Deployment Requests
To create the deployment of specific application, and `ApplicationDeploymentRequest` must be published. This request must reference the application to be deployed (`application`) and may optionally provide configuration (`config`) and a DNS name (`dns`). If no DNS name is supplied, one will be generated. A supplied DNS is usually just the short hostname, not the FQDN, since the suffix is supplied by the deployer.
```
$ cat req.yml
record:
type: ApplicationDeploymentRequest
version: 1.0.0
name: "my-org-name/my-test-webapp@0.1.5"
application: "crn://my-org-name/applications/my-test-webapp@0.1.5"
dns: "my-test-app"
config:
env:
CERC_WEBAPP_DEBUG: my_debug_value_here
$ laconic -c $LACONIC_CONFIG cns record publish -f req.yml
bafyreihtpvwjka5ecjmca46y4dip5gb2h25vvmc7t27d7g4zecngjssvky
```
It is not necessary to assign a name to the request.
## Building and Deploying
Building and deploying will happen automatically for records published the production registry, but in other environments it can be triggered manually.
Laconic `stack-orchestrator` is used build and launch the application. It will clone the repository, build the application, upload the container to a registry, and launch the instance in Kubernetes, with
automatic DNS and TLS provisioning.
```
$ laconic-so deploy-webapp-from-registry \
--kube-config $KUBE_CONFIG \
--image-registry registry.mydeployer.org/app-registry \
--deployment-parent-dir /opt/deployments \
--laconic-config $LACONIC_CONFIG \
--dns-suffix mydeployer.servesthe.world \
--record-namespace-dns crn://my-deployer-org/dns \
--record-namespace-deployments crn://my-deployer-org/deployments \
--request-id bafyreihtpvwjka5ecjmca46y4dip5gb2h25vvmc7t27d7g4zecngjssvky
```
When deployment is complete, an `ApplicationDeploymentRecord` will be created:
```
$ laconic -c $LACONIC_CONFIG cns name resolve crn://my-deployer-org/deployments/my-test-app.mydeployer.servesthe.world
[
{

}
}
]
```
## Checking Status
The status of the deployment may be checked with `stack-orchestrator`.
```
$ laconic-so deployment --dir /opt/deployments/my-test-app.snowball.servesthe.world status
Ingress:
Hostname: my-test-app.mydeployer.servesthe.world
IP: 204.130.133.199
TLS: notBefore: 2024-01-12T23:11:09Z, notAfter: 2024-04-11T23:11:08Z
Pods:
default/laconic-9560ffc64512e453-deployment-fb58d756f-l77pm: Running (2024-01-13 00:10:42+00:00)
```
# Removing Deployments
As with deployment, removal involves publishing a request, which is then fulfilled by deployment processor.
## Application Deployment Removal Requests
```
$ cat apprm.yml
record:
type: ApplicationDeploymentRemovalRequest
version: 1.0.0
deployment: bafyreiemfmxsue4svzys6tcwsqmhfjeyoo3gp63n7kydi2izbrwuzd4rga
$ laconic -c $LACONIC_CONFIG cns record publish -f apprm.yml
bafyreiejnqhsn5ibc3c6pzlsc26co3mt63djdeuntt3gmfuckcntdmisge
```
## Removal
As with deployment, for records publish to the production service removal should be processed automatically. In other environments, removal can be processed with `stack-orchestrator`.
```
$ laconic-so undeploy-webapp-from-registry \
--deployment-parent-dir /opt/deployments \
--laconic-config ~/.laconic/local.yml \
--request-id bafyreiejnqhsn5ibc3c6pzlsc26co3mt63djdeuntt3gmfuckcntdmisge
