ISSUE TYPE

• Bug Report

COMPONENT NAME

k8s

ANSIBLE VERSION

ansible 2.5.5
  config file = /work/ansible.cfg
  configured module search path = [u'/root/.ansible/plugins/modules', u'/usr/share/ansible/plugins/modules']
  ansible python module location = /usr/lib/python2.7/site-packages/ansible
  executable location = /usr/bin/ansible
  python version = 2.7.14 (default, Feb 22 2018, 21:59:35) [GCC 6.3.0]

CONFIGURATION

DEFAULT_HOST_LIST(/work/ansible.cfg) = [u'/work/inventories']
DEFAULT_ROLES_PATH(/work/ansible.cfg) = [u'/work/.imported_roles', u'/work/roles']
DEFAULT_VAULT_PASSWORD_FILE(/work/ansible.cfg) = /work/.build/ansible/vault-pass

OS / ENVIRONMENT

docker container running on Windows 10 based on williamyeh/ansible:alpine3 with the following additions:
apk: gcc, musl-dev, python2-dev
pip:* ansible, boto3, botocore, openshift
additionally: heptio-authenticator-aws

Ansible project directory is mounted to /work inside the container.

STEPS TO REPRODUCE

Using the files from https://gist.github.com/Tzrlk/b5ecafe3eb5adeabeed4796b5b33f1a9, attempt to deploy to the running cluster via docker run --rm -v /c/code/devops/ansible://work -e http_proxy=http://proxy:3128/ -e https_proxy=http://proxy:3128/ -e no_proxy=127.0.0.1,localhost,local tzrlk/ansible ansible-playbook -vvv playbooks/k8s_virginia.yml

EXPECTED RESULTS

Expected the resource to be applied in the same manner as kubectl apply -f

ACTUAL RESULTS

Instead, an "Incorrect Padding" error was produced, and playbook execution halted.

docker run --rm -v /c/code/devops/ansible://work -e http_proxy=http://proxy:3128/ -e https_proxy=http://proxy:3128/ -e no_proxy=127.0.0.1,localhost,local tzrlk/ansible ansible-playbook -vvv \

Looks like an issue with your ~/.kube/config file - it seems to be trying to base64 decode something that is not properly base64 encoded.

Without your kube config it's impossible to debug further. This is happening at the kubernetes python module level, well below the k8s module.

[Tzrlk]

I was afraid of that. I suspect it's the certificate data that's at fault, since the rest of the file looks perfect. Thanks for the identification.

[willthames]

You could probably confirm this by doing echo $cert_data | base64 -D and seeing if it looks like a proper certificate (should start with a line like -----BEGIN CERTIFICATE----- and end with -----END CERTIFICATE----- - the key will be similar, as will the CA)

I have this issue with OIDC-authorisation in python's kubernetes-client:
