GitHub user lhotari edited a comment on the discussion: Installing a custom
sink connector
Another solution would be to build a custom docker image with required
connectors in the image
1. Save this to a directory as `Dockerfile`
```Dockerfile
# example usage: docker buildx build --platform linux/amd64 --build-arg
PULSAR_IMAGE=apachepulsar/pulsar:4.0.3 -t myorg/pulsar:4.0.3-custom .
ARG PULSAR_IMAGE=apachepulsar/pulsar:latest
FROM ${PULSAR_IMAGE} AS pulsar
COPY /connectors /pulsar/connectors
```
2. Create `connectors` and download the connectors there.
```
mkdir connectors
cd connectors
curl -LO
https://github.com/streamnative/pulsar-io-lakehouse/releases/download/v4.0.3.1/pulsar-io-lakehouse-4.0.3.1.nar
```
3. Build and push the image
```
docker buildx build --push --platform linux/amd64 --build-arg
PULSAR_IMAGE=apachepulsar/pulsar:4.0.3 -t myorg/pulsar:4.0.3-custom .
```
(remove `--push` if you just want to test locally)
If you need arm64 support, add `--platform linux/amd64,linux/arm64`. To avoid
issues, pass `--push` to the command line when building multi-platform images
since otherwise you might not get a multi-platform image in your repository.
example of building and pushing multi-platform image:
```
docker buildx build --push --platform linux/amd64,linux/arm64 --build-arg
PULSAR_IMAGE=apachepulsar/pulsar:4.0.3 -t myorg/pulsar:4.0.3-custom .
```
And finally use this image in Apache Pulsar Helm chart as the default image
```yaml
defaultPulsarImageRepository: myorg/pulsar
defaultPulsarImageTag: 4.0.3-custom
```
It also replaces `apachepulsar/pulsar-all` with much smaller
`apachepulsar/pulsar` image. If you need all connectors, you can build a custom
image based on `apachepulsar/pulsar-all`.
