Is Docker generally solid enough for production deployment?

Most people use Ubuntu, it is the recommended OS.

We manage a few on-premise deployments on CentOS 7 (by customer request) without any issues.

Relevant parts of the Ansible role:

- name: add docker repository (CentOS)
  get_url:
    url: "https://download.docker.com/linux/centos/docker-ce.repo"
    dest: '/etc/yum.repos.d/docker-ce.repo'
    owner: root
    group: root
    mode: 0644
  when: ansible_distribution == 'CentOS'

- name: install docker
  package:
    name: "{{ item }}"
    state: present
  with_items:
  - docker-ce
  - docker-ce-cli
  - containerd.io

- name: ensure docker is started and enabled at boot
  service:
    name: docker
    state: started
    enabled: yes
