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:-
{
"Services": [{
"id": "somename",
"name": "nameofthissevice",
"service": "myservice",
"address": "127.0.0.1",
"port": 62133,
"enableTagOverride": false,
"tags" : ["service1"]
},
{
"id": "somename1",
"name": "nameofthissevice",
"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 ?

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

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

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).
I am following the below to set up a config server in PCF and access the application in PCF.
https://github.com/pcf-guides/gs-configuration-server
I have added the config server from the PCF marketplace and it is bind with the app.
The config server is pointed to the following Git repository:
https://github.com/pcf-guides/configuration-server-config-repo.git
The VCAP_SERVICES is like below :

Whenever I am trying to access the application authentication error is coming :
Full authentication is required to access this resource.
I dont have any security configuration in the application.
In your application.properties file, you should add the following
management.security.enabled=false
This will disable security altogether.
I tried this in my main application class and worked fine for me
#SpringBootApplication(exclude = {SecurityAutoConfiguration.class , ManagementWebSecurityAutoConfiguration.class})
Hi I am unable to connect mysql to apache drill on vm.
I have used jdbc connector 5.1.45 and mysql version is 5.7.20.
Also in VM its giving warning:
Download mysql-connector-java-5.1.37-bin.jar connector and place it in jars/3rdparty/ folder
Modify conf/drill-override.conf to add the below line before }:
drill.exec.sys.store.provider.local.path = "mysql-connector-java-5.1.37-bin.jar"
Restart drill and try again.
Storage plugin should look something like this:

"driver": "com.mysql.jdbc.Driver",
"url": "jdbc:mysql://localhost:3306",
"username": "username",

I don't understand the problem.VPSs are not locally connected. All are public IP.I don't know, this may b an issue. how do I make virtual LAN among these VPS?Can anyone give me some direction about this error?Anyone helps me is greatly appreciated.
Edit: I used VM term insted of VPS.
Finally I make this working. Actually all the nodes are in a network, i thought it wasn't. I enable file sharing. I try to access the shared file from the node where I ran configuration test to the all other nodes. I have to give the credentials of logins. And then it works like a charm.
