Thanks for pointing to the `make images`, I was able to build the image
locally with pre-downloaded dependencies. And install it to the Minikube by
loading the image inside:
```
minikube image load docker.io/apache/camel-k:2.0.0-SNAPSHOT
```
But I wasn't able to create an integration because during it's creation it
couldn't resolve parent POM `org.apache:apache:pom:29` for
`org.apache.camel.k:camel-k-runtime-bom:1.17.1-SNAPSHOT`
```

I took a look around the pre-downloaded dependencies and noticed that there
were `org.apache:apache:pom` lying around but just up to 28, so I changed 29
into 28 inside the dowloaded
`org.apache.camel.k:camel-k-runtime-bom:1.17.1-SNAPSHOT.pom` manually. It made
some progress but still was trying to download more missing dependencies, there
was quite a lot of them and it was too tedious to figure them out one by one,
although I think eventually I would be able to make it work.

So what I decided to do is use a messy hack:
1. Use cluster with internet as staging ground for developing and testing
integrations using the stock releases of camel-k, not my locally modified one.
2. Inside the camel-k-operator it stores all the dependencies needed for
creating integrations in `/tmp/artifacts`.
3. Copy the whole directory from inside the pod to the host
```
kubectl cp default/CAMEL_K_OPERATOR_POD_NAME:/tmp/artifacts /your/host/path
```
4. Install the camel-k-operator inside the air-gapped cluster without
internet, you need to point to your docker registry that is installed inside
your cluster (I'm using nexus docker registry) and put
`docker.io/apache/camel-k:RELEASE_VERSION` image inside it so that kamel can
resolve it without internet. Also you need to put 'adoptopenjdk/openjdk11:slim'
there too as it is used for creating integrations
```
kamel install --registry YOUR_REGISTRY:5000 --registry-auth-username
USERNAME --registry-auth-password
PASSWORD --registry-insecure true --base-image
YOUR_REGISTRY:5000/adoptopenjdk/openjdk11:slim
```
5. Move the directory to the air-gapped cluster and copy it inside the
installed camel-k-operator pod at this location `/tmp/artifcats`.
6. After all the steps I was able to create integrations without internet!
As I understand `/tmp/artifacts` is a default location for the local maven
repository if you don't provide one when doing `kamel install`. If you do
provide it I think you could do the same thing by copying from staging maven
repository to air-gapped one.
This feels hacky but at least I was able to make it work
