kameshsampath opened a new issue #498: Knative pods not scaling down to zero URL: https://github.com/apache/camel-k/issues/498 I am deploying the route like: // content based router Route 1 ``` from("aws-s3://data?deleteAfterRead=false") .streamCaching() .filter(header("CamelAwsS3Key").endsWith(".xml")) .idempotentConsumer(header("CamelAwsS3ETag"), idmRepo()) .log(LoggingLevel.DEBUG,"Processing File : ${header.CamelAwsS3Key}") .choice() .when(xpath("/person/country = 'US'")) .log("Sending Body ${body}") .to("knative:channel/messages-us") .otherwise() .log("Sending Body ${body}") .to("knative:channel/messages-others") .end(); ``` // us messages handler ``` from("knative:channel/messages-us") .log(LoggingLevel.DEBUG, "Received content ${body}") .setProperty("userName", xpath("/person/@user", String.class)) .convertBodyTo(byte[].class) .log(LoggingLevel.DEBUG,"Writing file {{messagesDir}}/${property.userName}.xml") .to("file://{{messagesDir}}/us?fileName=${property.userName}.xml") .end(); from("file:{{messagesDir}}?noop=true&recursive=true") .log(LoggingLevel.DEBUG,"Processing file ${in.header.CamelFileName}") .setHeader(S3Constants.CONTENT_LENGTH, simple("${in.header.CamelFileLength}")) .setHeader(S3Constants.KEY, simple("${in.header.CamelFileNameOnly}")) .convertBodyTo(byte[].class) .process(exchange -> { //Build a valid destination bucket name String camelFileRelativePath = exchange.getIn().getHeader("CamelFileRelativePath", String.class); String onlyPath = "us-out"; if (camelFileRelativePath != null) { log.debug("Camel File Relative Path " + camelFileRelativePath); onlyPath = FileUtil.onlyPath(camelFileRelativePath); log.debug("Camel File onlyPath " + onlyPath); } exchange.setProperty("toBucketName", "messages-"+ onlyPath.toLowerCase()); }) .log("Uploading file ${header.CamelFileName} to bucket: ${property.toBucketName}") .toD("aws-s3://${property.toBucketName}?deleteAfterWrite=false") .end(); ``` //other messages handler ``` // @formatter:off from("knative:channel/messages-others") .log(LoggingLevel.DEBUG,"Received content ${body}") .setProperty("userName", xpath("/person/@user", String.class)) .convertBodyTo(byte[].class) .log(LoggingLevel.DEBUG,"Writing file {{messagesDir}}/${property.userName}.xml") .to("file://{{messagesDir}}/others?fileName=${property.userName}.xml") .end(); from("file:{{messagesDir}}?noop=true&recursive=true") .log(LoggingLevel.DEBUG,"Processing file ${in.header.CamelFileName}") .setHeader(S3Constants.CONTENT_LENGTH, simple("${in.header.CamelFileLength}")) .setHeader(S3Constants.KEY, simple("${in.header.CamelFileNameOnly}")) .convertBodyTo(byte[].class) .process(exchange -> { //Build a valid destination bucket name String camelFileRelativePath = exchange.getIn().getHeader("CamelFileRelativePath", String.class); String onlyPath = "others-out"; if (camelFileRelativePath != null) { log.debug("Camel File Relative Path " + camelFileRelativePath); onlyPath = FileUtil.onlyPath(camelFileRelativePath); log.debug("Camel File onlyPath " + onlyPath); } exchange.setProperty("toBucketName", "messages-"+ onlyPath.toLowerCase()); }) .log("Uploading file ${header.CamelFileName} to bucket: ${property.toBucketName}") .toD("aws-s3://${property.toBucketName}?deleteAfterWrite=false") .end(); // @formatter:on ``` The Knative Camel-k setup works fine and was able to do what the route needed to. but once there are no more messages that is available I dont see the `usmessages` and `others-messages` handler knative pods scaling down to `0`
