Jupyterlab terminal not working kernel not loaded - bash

I am deploying the jupyterlab on k8s, it uses below kernel.json and creates runtime connection file and load kernel once start the notebook, console and pyspark, however i didnt find runtime connection file when starting terminal.
for example if I load notebook then the runtime file created as below:
/opt/spark/work-dir/.local/share/jupyter/runtime/kernel-xxxxxxxxxxxx-4x9e-xxx5-b32f7xxxxxx.json
{
"shell_port": 37215,

}
}
There is no error reported on log for this failure, I am only getting this message whenever loading the Terminal.

unable to control swarm ingress network with ansible

I'm deploying Docker swarm with ansible and I would like to ensure the ingress network has been created. In that aim, I configured the following task :
- name: Ensure ingress network exists
docker_network:
state: present
name: ingress
driver: overlay
driver_options:
ingress: true
And I'm getting the following error :
An exception occurred during task execution. To see the full traceback, use -vvv. The error was: docker.errors.NotFound: 404 Client Error for http+docker://localhost/v1.41/networks/ingress/disconnect: Not Found ("No such container: ingress-endpoint")
fatal: [swarm-srv-1]: FAILED! => {"changed": false, "msg": "An unexpected docker error occurred: 404 Client Error for http+docker://localhost/v1.41/networks/ingress/disconnect: Not Found (\"No such container: ingress-endpoint\")"}
I've tried to add some arguments likes :
scope: swarm
force: yes
But no changes... I've also tried to delete the ingress with ansible (state: absent), but I always get the same error.
Note that I don't face any issue when trying to delete a recreate the ingress network manually on the swarm : docker network rm ingress
I don't know how to resolve that issue...Any help would be appreciated. Thanks !
Here are some informations that may help...

I had the exact same issue when trying to customize the IP range of the ingress network. It looks like the docker_network module does not support modification of swarm specific networks: there is a open Github issue for this.
I went for the ugly workaround of removing the network by executing it through a shell (docker network rm ingress command) and adding it again. When adding it with the docker_network module, I found that adding also seems not be working (fails to set the ingress property of the network). So I ended up doing both remove- and create operation through a shell command.
Since the removal will trigger a confirmation dialogue:
WARNING! Before removing the routing-mesh network, make sure all the nodes in your swarm run the same docker engine version. Otherwise, removal may not be effective and functionality of newly create ingress networks will be impaired.
Are you sure you want to continue? [y/N]
I used the expect module to confirm the dialogue:
- name: remove default ingress network
ansible.builtin.expect:
command: docker network rm ingress
responses:
"[y/N]": "y"
- name: create customized ingress network
shell: "docker network create --ingress --subnet {{ docker_ingress_network }} --driver overlay ingress"
It is not perfect but it works.
There was one last problem I experienced: when running it on an existing swarm I ended up having network issues on the node where I did run this (somehow the docker_gwbridge network on that node could not handle the change). The fix for this was to fully remove the node and re-join the swarm (regenerates the docker_gwbridge).

Debug file other than main.go in VS Code

I am writing a CLI in go using VS code editor. I am not able to figure out how to debug a code section.
My directory structure is :
- test
- main.go
- cmd
- login.go
- root.go
I have set breakpoints in login.go but if I run "Start Debugging" in this file, I get error
Can not debug non-main package
Process exiting with code: 1
I tried running debugger in main.go but the debugger won't go to login.go file as I we have not explicitly written test login
API server listening at: 127.0.0.1:48423
A longer description that spans multiple lines and likely contains
examples and usage of using your application. For example:
cd .

This application is a tool to generate the needed files
to quickly create a Cobra application.
Usage:
test [command]
Available Commands:

login A brief description of your command
Flags:
--config string config file (default is $HOME/.test.yaml)
-h, --help help for test
-t, --toggle Help message for toggle
Use "test [command] --help" for more information about a command.

Please guide me how I can see the variable values in debug mode like for variable name. Though using Println is fine, but this source code is part of a bigger project, so I want to see how I can use the debugger ?
Modify your launch.json as below:
{
"version": "0.2.0",
"configurations": [
{
"name": "Launch",
"type": "go",
"request": "launch",
"mode": "debug",
"program": "${workspaceRoot}",
"env": {},
"args": [],
"port": 8080,
"host": "127.0.0.1"
}
]
}
You'll learn that some differences are there from yours.
...
"mode": "debug",
"program": "${workspaceRoot}",
...
You can add flags to the "args": [] array in your vscode settings like this:
"args": ["login", "-u", "username", "-p", "password"]
This will make sure when you run debug you end up in the login command with the given flags.

Multiple Service Definition in Config File Not Working Consul

I have been trying to add multiple service through configuration in consul.
But Consul UI is throwing error at startup of the agent itself.
The error is:-
$consul.exe agent --dev
Starting Consul agent...
panic: runtime error: invalid memory address or nil pointer dereference
github.com/hashicorp/consul/agent.(*Agent).loadServices(0xc0421268c0,

Config file is:-

},
{

"service": "myservice2",
"address": "127.0.0.1",
"port": 64921,
"enableTagOverride": false,
"tags" : ["service2"]
}]
}
I am using Win 7 platform.
Could any one suggest some ideas in it.
Thx
The configuration file is not loaded, so the problem is not in the file, in order to load the configuration file you should add another flag for loading the configuration, otherwise consul will start with default configuration.
Looks like a faulty binary or incompatible version.
Your windows7 is a 32 bit arch or 64?
And which exec version of consul have you downloaded ?

Debug Electron using Visual Studio Code on Mac

Refer to this stackoverflow question:
I am trying to do the same but on Mac. I have the same as above,except instead of
"runtimeExecutable": "node_modules/electron-prebuilt/dist/electron.exe"
I have it as
"runtimeExecutable": "/usr/local/bin/electron"
Since F5 on mac is mapped to screen dimmer, I launched the app from command line as follows:
electron --debug-brk=5858 .
My program launched and ran without breaking.
So I modified keybindings.json like so:
[
{ "key": "shift+ctrl+f5", "command": "workbench.action.debug.play",
"when": "inDebugMode" },
{ "key": "shift+ctrl+f5", "command": "workbench.action.debug.start",
"when": "!inDebugMode" },
]
I tried launching the program by pressing shift+ctrl+f5 - I am still unable to debug my program.
I get the following error:
Error: Connection Failed
when I run node instead of electron, the debugger works fine when the the app is launched from command line
PLEASE HELP!
Thanks in advance
This is your launch.json. The important parts are runtimeExecutable and env. For VS Code 0.8.0, debugging only mostly works using electron 0.30.6.
