You should be able to use hclose as it is here:

Based on the error message, the parent-last version looks like it's failing because there is a copy of the Servlet API packaged in your application. This is not a usable configuration, because the container will link to its own copy of the API, and as a result it wouldn't be able to successfully cast application artifacts that link to their own API instance. There are some APIs for which you can bring your own version in the app, but Servlet is not among them.

For the parent-first failure, it looks like Spring is expecting a newer version of the javax.validation package than is provided by the server - it's calling a method that doesn't exist in the server's version. WebSphere 8.5.5 implements Java EE 6, which includes Bean Validation 1.0, and that method wasn't added until Bean Validation 1.1. You'll need a version of Spring that works with Java EE 6 or is configurable to avoid higher-version dependencies. It might also be possible to resolve this by running parent-last and including a separate implementation along with the API (obviously, removing the Servlet API as referenced in the previous paragraph), although I'm not familiar enough with the Bean Validation API to know whether that would cause a conflict with the server runtime in the same way as Servlet.

Stunnel can be used to encrypt or decrypt any TCP SSL connection, including websockets.

To get KDB to connect to a secure websocket, you need to use stunnel in client mode.

This is the config that worked for me. You can then open the decrypted websocket on your localhost at ws://localhost:80

you should create a file and you can use

COPY index.html index.html

command into Dockerfile to copy a file into image when build

or use

echo " " > index.html command to create a file

Command target_include_directories and include_directories affects on compilation, but doesn't affect on checking headers via CHECK_INCLUDE_FILE_CXX.

For hint the macro CHECK_INCLUDE_FILE_CXX to search in additional include directories, set variable CMAKE_REQUIRED_INCLUDES:

First of all, You could create a directory and the logfile itself. If the count-log-1 container spin up first, it will have nothing to read and exit with an error. To to it, a good practise is to use an Init Container. https://kubernetes.io/docs/concepts/workloads/pods/init-containers/

Second, containers need to have a shared volume, on which the logfile will be present. If there is no need to persist data, an emptyDir volume will enough. https://kubernetes.io/docs/concepts/workloads/pods/init-containers/

Finally, You hade some errors in shell commands. Full .yaml file:

I was able to reproduce this when I ran through vcfg and specified https, but then did what you did and passed the bind-web-address to the volttron command itself.

However, you shouldn't do this. The instructions assume you haven't gone through the vcfg process and therefore you would have to specify the bind web address on the command line.

Since you went through the vcfg process your config file (~/.volttron/config) will have your hostname:port as the bind-web-address. If it has https in it that is the reason it is not working for you.

I fixed My problem by running CMake with one additional parameter.

Few things to consider here:

1. print statements to stdout won't necessarily show in your output with Flask, I believe stderr does, so you might want to try either that or the logger, e.g.:
