When I run the following Ansible playbook on my backup server,
backups.example.com, I get the error shown below:
# main.yml
---
- name: restore database
hosts: dbserver.example.com
gather_facts: false
vars:
me: smith
tasks:
- command: rsync -vz /path/to/db.dump {{ me
}}@dbserver.example.com:/tmp
become: true
become_user: "{{ me }}"
Error:
fatal: [dbserver.example.com] => SSH Error: data could not be sent to
the remote host. Make sure this host can be reached over ssh.
Yet I can run the command manually from my backup server, it succeeds:
rsync -vz /path/to/db.dump [email protected]:/tmp
Here are the pertinent files:
# ansible.cfg
[defaults]
inventory = inventory.ini
host_key_checking = False
ssh_args = -o UserKnownHostsFile=/dev/null
[ssh_connection]
pipelining = True
# inventory.ini
[dbservers]
dbserver.example.com ansible_ssh_host=<dbserver_ip_address>
ip_addr=<dbserver_ip_address>
[local]
localhost ansible_connection=local
# ~/.ssh/config
Host dbserver.example.com
# I know this creates a security risk but I don't know how else to
handle the "authenticity of host..." prompt when running an Ansible playbook
StrictHostKeyChecking no
User smith
I've checked and there is an entry for dbserver.example.com in the
~/.ssh/known_hosts file. My public key is installed in the authorized_keys
file on the remote dbserver.
I've researched this online and read the Ansible documents but I don't see
what I'm doing wrong. Initially I tried using the Ansible synchronize
module but it produced the same error. I also tried using the "-vvvv"
option with my ansible-playbook command but the output didn't yield any
useful information. All I say was the command stop at a certain point.
What am I missing here?
