I'm trying to follow along this blog about using Docker with R.
I followed basic Docker set up steps and am able to run the hello world image.
I'm on a old 2009 Mac and had to use Docker Toolbox.
I'm in a place with weak internet connection and am using a personal hotspot.
Each time I try to run docker run --rm -p 8787:8787 rocker/verse I wait for a few minutes and see a downloading message, then I get a message "docker: unauthorized: authentication required."
I found this separate documentation which advised me to add a password:
docker run --rm -p 8787:8787 -e PASSWORD=blah rocker/rstudio
But I got the same result "docker: unauthorized: authentication required."
I did some Google searching and found some posts both here on SO and on Github but was unable to identify what is causing this error in my specific case.
I suspect my weak internet connection might have something to do with it since I seem to be able to download for about 10 or 15 minutes before seeing this message.
Here is Docker info:

Writing ansible playbook for "Count number of users currently login to VPN".Using Junos modules as suggested by network team.I have installed below softwares on my RHEL 7 machine with Ansible 2.9 version installed.
Junos Ansible Requirements
===============================
-->Install Dependencies
# pip install ncclient
# pip install junos-eznc
--> Install Juniper.junos Galaxy role
ansible-galaxy install juniper.junos
---> Have NETCONF enabled on Juniper devices over SSH
# set system services netconf ssh
--->(Optional)
#pip install junos-netconify (python lib for juniper console)
Whenever i am writing any playbook, I am getting below error.
Playbook:-
---
- name: Get device uptime
hosts:
- dc1
roles:
- Juniper.junos
connection: local
gather_facts: no
vars_prompt:

tasks:
- name: get uptime using galaxy module
junos_command:
commands: show system uptime
register: uptime
- name: display uptimes
debug: var=uptime
Error:-

I was just exploring ansible networking commands & got above error.Please suggest what configurations required working with junos.
Please find below playbook to check no. of users currently login to VPN:-
name: Get system users currently logged in
hosts: all
connection: local
gather_facts: no

I am writing a playbook, which dynamically enters the network servers provided by user at prompt in host file.Further i want to create a task which will ssh on the server one by one and run show version command to fetch the OS of those network devices.
As of now, I am getting the below error:
1."Unable to automatically determine host network os. Please manually configure ansible_network_os value for this host"
I dont want to define the OS beforehand, rather want the playbook to do it.
I tried entering some configurations in host file as below:
[device]
192.1xx.xxx.xx
[all:vars]
ansible_connection=network_cli
ansible_user=user
ansible_ssh_pass=password
ssh_args = -o GSSAPIAuthentication=no
The below plsybook is taking device name from the user and adding it to the file, further it need to ssh on those servers and fetch the OS details:
---
- name: add host dynamically
hosts: localhost
gather_facts: no
vars:
Server: null_val1
vars_prompt:
- name: "Server"
prompt: "Please enter the non-reporting server/IP"
private: no
default: null_val1
pre_tasks:
- name: Save variable
set_fact:
Server: "{{Server}}"
- name: Copying servers to host file
hosts: localhost
become: true
tasks:
- name: copying variable value
lineinfile:
path: "{{playbook_dir}}/hosts.txt"
line: "{{Server}}"
insertafter: '^\[device\]'
state: present
- name: Main execution task
hosts: device
gather_facts: true
tasks:
- name: Run command on devices
cli_command:
command: show version
register: result
- name: display result
debug:
var: result.stdout_lines
The actual result should show me the OS of network device(s) entered in host file by running show version command remotely.
I am trying to create a simple hosting platform for my clients. I am deploying all of my apps via docker on a VPS behind nginx-proxy. For wordpress applications I want to be able to limit disk-space so that my clients do not use too much and affect other applications. I bind mount all volumes to a single directory so that I can back-up easily with cron.
I've change the file system to overlay2 and am on centos 7.
[root#my-ip ~]# docker info
Server:
Containers: 12
Running: 12
Paused: 0
Stopped: 0
Images: 11
Server Version: 19.03.1
Storage Driver: overlay2
Backing Filesystem: xfs
Supports d_type: true
Native Overlay Diff: true
When I run a wordpress container with the --storage-opt size=10G I get the following error:
docker: Error response from daemon: --storage-opt is supported only for overlay over xfs with 'pquota' mount option.
This is an example of the bind mount I am using:
-v /DOCKER_VOLUMES/wordpress/appname/www/html:/var/www/html
How do I fix this? Can you please provide a full list of instructions to enable it?
from the Docs:
This (size) will allow to set the container rootfs size to 120G at creation time. This option is only available for the devicemapper, btrfs, overlay2, windowsfilter and zfs graph drivers. For the devicemapper, btrfs, windowsfilter and zfs graph drivers, user cannot pass a size less than the Default BaseFS Size. For the overlay2 storage driver, the size option is only available if the backing fs is xfs and mounted with the pquota mount option. Under these conditions, user can pass any size less than the backing fs size.
so the pquota should be enabled on your system
you can edit the file /etc/default/grub like so, and restart your machine:
GRUB_CMDLINE_LINUX_DEFAULT="rootflags=uquota,pquota"
and try to rerun your command with --storage-opt size=10G
I am trying to using the ntc-ansible module with Ansible running on Ubuntu (WSL). I have ssh connectivity to my remote device (Cisco 2960X) and I can run ansible playbooks to the same remote switch using the built in Ansible networking modules (ios_command) and it works fine.
Issue:
When I try to run any of the ntc-ansible modules, it fails, unable to connect to the device. Probably something simple, but I have hit a wall. There is something I am missing about how to use ntc-ansible modules. Ansible is seeing the modules as I can look at the docs as was suggested as a test in the readme.
I have ntc-ansible module installed here: /home/melshman/.ansible/plugins/modules/ntc-ansible
I am running my playbooks from here: ~/projects/ansible/
The first time I ran the playbook with the ntc-ansible modules it failed and based on error message and some research I installed sshpass (sudo apt-get install sshpass). But still having ssh problems using ntc-ansible… (playbook and traceback below)
I hear folks taking about an index file, but I can’t find that file? Where does it live and what do I need to do with it?
What is my connection supposed to be setup to be? Local? SSH? Netmiko_ssh?
What should I be using for platform? Cisco_ios? cisco_ios_ssh?
Appreciate any help I can get. I have been running in circles for hours and hours.

Here is a working solution using ntc_show_command to a Cisco IOS device.
- name: Cisco IOS Automation
hosts: pynet-rtr1
connection: local
gather_facts: no
tasks:
- name: GET UPTIME
ntc_show_command:
connection: ssh
platform: "cisco_ios"
command: 'show version'
host: "{{ ansible_host }}"
username: "{{ ansible_user }}"
password: "{{ ansible_ssh_pass }}"
use_templates: True
template_dir: '/home/kbyers/ntc-templates/templates'
If you are going to use ntc-templates, I probably would not have the '| include uptime' in the 'show version'. In other words, let TextFSM convert the output to structured data first and then grab the uptime from that structured data.
I modified inventory_hostname to ansible_host to be consistent with my inventory format (my inventory_hostname doesn't actually resolve in DNS).
I modified username and password to 'ansible_user' and 'ansible_ssh_pass' to be consistent with my inventory and also to be more consistent with Ansible 2.5/2.6 variable naming.
On your above issue, your exception message does not match your playbook (i.e. are you sure that is the exception you get for that playbook).
Here is my inventory file (I simplified this to remove some unnecessary devices and to hide confidential information)
[all:vars]
ansible_connection=local
ansible_python_interpreter=/home/kbyers/VENV/ansible/bin/python
ansible_user=user

Would be happy for any ideas. My search was not successful so far.
it seems like you want to mount a file to a file. i remember on your docker-version its not allowed. you have to move your nginx.conf inside of your Dockerfile
Dockerfile:
....
ADD nginx.conf /tmp/
RUN mv /tmp/nginx.conf /etc/nginx/nginx.conf && \
....
this should work for you. if not show me your next error code
I faced similar issue due to volume mount was not worked properly.
So docker default behavior consider this /nginx.conf as directory and gives this error.
To confirm this, you can ssh into your image and go to shared directory and check the files exist or not.
Example: docker exec -it nginx sh and go to /etc/nginx/html you won't see your local files. Then you can confirm volume share was not working. you need to fix that.
If you are using windows 10 (hyper-v), first you need to share your drive and check.
However you need to find the solution to mound your shared directory first.
