I am currently developing a project where I need to get the pod names of a Kubernetes Cluster running on Rancher using Ansible. The main thing here is that I have a couple of problems that are preventing me from advance.
I am currently executing a playbook to try to retrieve this information, instead of running a CLI command, because I want to manipulate those Rancher machines later one (e.g. install an rpm file).
Here is the playbook that I am executing tot try to retrieve the pods' names from Rancher:
---
- hosts: localhost
connection: local
remote_user: root
roles:
- role: ansible.kubernetes-modules
- role: hello-world
vars:
ansible_python_interpreter: '{{ ansible_playbook_python }}'
collections:
- community.kubernetes
tasks:
-
name: Gather openShift Dependencies
python_requirements_facts:
dependencies:
- openshift
-
name: Get the pods in the specific namespace
k8s_info:
kubeconfig: '/etc/ansible/RCCloudConfig'
kind: Pod
namespace: redmine
register: pod_list
-
name: Print pod names
debug:
msg: "pod_list: {{ pod_list | json_query('resources[*].status.podIP') }} "
- set_fact:
pod_names: "{{pod_list|json_query('resources[*].metadata.name')}}"
The problem is that I am getting a Kubernetes module error each time I am trying to run the playbook:
ERROR! the role 'ansible.kubernetes-modules' was not found in community.kubernetes:ansible .legacy:/etc/ansible/roles:/home/jcp/.ansible/roles:/usr/share/ansible/roles:/etc/ansible/ roles:/etc/ansible
The error appears to be in '/etc/ansible/GetKubectlPods': line 7, column 7, but may
be elsewhere in the file depending on the exact syntax problem.
The offending line appears to be:
roles:
- role: ansible.kubernetes-modules
^ here
If I remove that line on the code, Where I try to retrieve that role, I still get a similar error:
An exception occurred during task execution. To see the full traceback, use -vvv. The error was: ModuleNotFoundError: No module named 'kubernetes'
fatal: [localhost]: FAILED! => {"changed": false, "error": "No module named 'kubernetes'", "msg": "Failed to import the required Python library (openshift) on localhost.localdomain's Python /usr/bin/python3.6. Please read module documentation and install in the appropriate location. If the required library is installed, but Ansible is using the wrong Python interpreter, please consult the documentation on ansible_python_interpreter"}
I have already tried to install ansible-galaxy kubernetes module on the machine and openshift.
Not sure what I am doing wrong since there are so many possibilities for what could be going wrong here.

Thanks for your help in advance!
Edit: The below answer was given for OP's specific Ansible version (i.e. 2.9.9) and is still valid if you still use it. Since version 2.10, you also need to install the relevant ansible collection if not already present
ansible-galaxy collection install kubernetes.core
See the latest module documentation for more information
In Ansible 2.9.9, you're not supposed to do anything special to use the module except installing the needed python dependencies. See the module documentation for your Ansible version
remove the line - role: ansible.kubernetes-modules, unless it is a module of yours in which case you have to tell us more because this is not a correct declaration.
remove the collection declaration
Add the following task somewhere before using the module:
- name: Make sure python deps are installed
pip:
name: openshift
Your actual python_requirement_facts task is doing nothing else than reporting the dependency is not found. Register the result and debug it to see for yourself.
Now use the k8s_info module normally.
I've deployed nodejs based IBM cloud function using manifest file. I'll have few other functions which may share some common codes. Here is the folder structure
manifest.yml
actions/
- myFunction1/
-- index.js
-- package.json
- myFunction2/
-- index.js
-- package.json
- common/
-- utils.js
Here is my manifest.yml -
packages:
myfunctions:
version: 1.0
license: Apache-2.0
actions:
myFunction1:
function: actions/myFunction1
runtime: nodejs:10
include:
- ["actions/common/*.js", "./common/"]
myFunction2:
function: actions/myFunction2/index.js
runtime: nodejs:10
I deployed the functions using following command from cmd-
ibmcloud fn deploy --manifest manifest.yml
The deployment went successful, both functions are created. Second function(myFunction2) executes properly but the first function throws error when try to execute. Here is the error message -
{
"error": "Initialization has failed due to: There was an error uncompressing the action archive."
}
I even tried with the inclusion of the dependencies in manifest and codes but throws same error. I was following this article -
https://medium.com/openwhisk/whisk-deploy-zip-actions-with-include-exclude-30ba6d96ad8b
Still struggling, appreciate any help.
Thanks

I get an appcrash when attempting to install arangoDB in on a windows 7 machine. I have also tried the XCOPY version and have the same issue. The APPCRASH gives the following:

I do not believe it even attempts to access the arangod.conf file let alone object to something inside it.
I used Windows debugger to try and get some additional clues but I'm left stumped. The results are here: http://textuploader.com/do6wn
Please use github issues for these kind of problems.
We are using some community custom resource types (https://github.com/ljfranklin/terraform-resource and https://github.com/cloudfoundry/bosh-deployment-resource). After upgrading to concourse 3.3.0, we've begun consistently seeing the following error on a few of our jobs at the same step: json: unsupported type: map[interface {}]interface {}.
This is fairly hard to debug as there is no other log output other than that. We are unsure what is incompatible between those resources and Concourse.
Notes about our pipeline:
We originally had substituted all of our usages of {{}} to (()), but reverting that did not lead to the error going away.
We upgraded concourse from v3.0.1.
The failing step can be found here: https://github.com/cloudfoundry/capi-ci/blob/6a73764d09f544820ce39f16dca166d6d6861996/ci/pipeline.yml#L731-L739
We are using a resource called elsa-aws-storage-terraform, found here: https://github.com/cloudfoundry/capi-ci/blob/6a73764d09f544820ce39f16dca166d6d6861996/ci/pipeline.yml#L731-L739
That resource is of a custom resource-type terraform found here: https://github.com/cloudfoundry/capi-ci/blob/6a73764d09f544820ce39f16dca166d6d6861996/ci/pipeline.yml#L45-L48

This is related to issue of not being able to define nested maps in resource configuration https://github.com/concourse/concourse/issues/1345
I'm trying to push an app to Bluemix on a Linux OS. However, the command line returns an error involving the manifest file:
Error reading manifest file:
Expected services to be a list of strings.
Here is the code for the manifest file:
applications:
- name: IdeaSocial
memory: 1024M
instances: 1
host: IdeaSocial
domain: mybluemix.net
path: .
services:
-SQL Database-v5
How do I fix this? Is there a form that the file needs to be in for the current version of Bluemix?
Add quotes around SQL Database-v5 to have it treated as a single string even though there is a space in it. Spaces matter in YAML.
...
services:
- "SQL Database-v5"
The documentation has more information and examples.
