autond

Project description

auton project

auton is a free and open-source, we develop it to run programs and command-lines on remote servers through HTTP protocol. There are two programs, auton for client side and autond for server side. auton is just a helper to transform command-lines into HTTP protocol, it is able to transform basic arguments, file arguments and environment variables. For example, you can use auton from CI/CD to run on remote servers, you just need to configure your endpoints:

  • ansible
  • curl
  • terraform You can also use auton if you need to execute a new version of a software but you can't install it on a legacy server.

Quickstart

Autond configuration

See configuration example etc/auton/auton.yml.example

Endpoints

In this example, we declared three endpoints: ansible-playbook-ssh, ansible-playbook-http, curl. They used subproc plugin.

endpoints:
  ansible-playbook-ssh:
    plugin: subproc
    config:
      prog: ansible-playbook
      timeout: 3600
      args:
        - '/etc/ansible/playbooks/ssh-install.yml'
        - '--tags'
        - 'sshd'
      become:
        enabled: true
      env:
        DISPLAY_SKIPPED_HOSTS: 'false'
  ansible-playbook-http:
    plugin: subproc
    config:
      prog: ansible-playbook
      timeout: 3600
      args:
        - '/etc/ansible/playbooks/http-install.yml'
        - '--tags'
        - 'httpd'
      become:
        enabled: true
      env:
        DISPLAY_SKIPPED_HOSTS: 'false'
  curl:
    plugin: subproc
    config:
      prog: curl
      timeout: 3600

Authentication

To enable authentication, you must add auth_basic and auth_basic_file lines in section general:

general:
  auth_basic:      'Restricted'
  auth_basic_file: '/etc/auton/auton.passwd'

To generate auth_basic_file use htpasswd: htpasswd -c -s /etc/auton/auton.passwd foo

And you have to add for each modules route auth: true:

modules:
  job:
    routes:
      run:
        handler:   'job_run'
        regexp:    '^run/(?P<endpoint>[^\/]+)/(?P<id>[a-z0-9][a-z0-9\-]{7,63})$'
        safe_init: true
        auth:      true
        op:        'POST'
      status:
        handler:   'job_status'
        regexp:    '^status/(?P<endpoint>[^\/]+)/(?P<id>[a-z0-9][a-z0-9\-]{7,63})$'
        auth:      true
        op:        'GET'

Use section users to specify users allowed by endpoint:

  ansible-playbook-ssh:
    plugin: subproc
    users:
      maintainer: true
      bob: true
    config:
      prog: ansible-playbook
      timeout: 3600
      args:
        - '/etc/ansible/playbooks/ssh-install.yml'
        - '--tags'
        - 'sshd'
      become:
        enabled: true
      env:
        DISPLAY_SKIPPED_HOSTS: 'false'

Plugin subproc

subproc plugin executes programs with subprocess.

Use keyword proc to specify program path:

endpoints:
  curl:
    plugin: subproc
    config:
      prog: curl

Use keyword workdir to change the working directory:

endpoints:
  curl:
    plugin: subproc
    config:
      prog: curl
      workdir: somedir/

Use keyword search_paths to specify paths to search prog:

endpoints:
  curl:
    plugin: subproc
    config:
      prog: curl
      search_paths:
        - /usr/local/bin
        - /usr/bin
        - /bin

Use section become to execute with an other user:

endpoints:
  curl:
    plugin: subproc
    config:
      prog: curl
      become:
        enabled: true
        user: foo

Use keyword timeout to raise an exception after n seconds (default: 60 seconds):

endpoints:
  curl:
    plugin: subproc
    config:
      prog: curl
      timeout: 3600

Use section args to define arguments always present:

endpoints:
  curl:
    plugin: subproc
    config:
      prog: curl
      args:
        - '-s'
        - '-4'

Use keyword disallow-args to disable arguments from client:

endpoints:
  curl:
    plugin: subproc
    config:
      prog: curl
      args:
        - '-vvv'
        - 'https://example.com'
      disallow-args: true

Use section argfiles to define arguments files always present:

endpoints:
  curl:
    plugin: subproc
    config:
      prog: curl
      argfiles:
        - arg: '--key'
          filepath: /tmp/private_key
        - arg: '-d@'
          filepath: /tmp/data

Use keyword disallow-argfiles to disable arguments files from client:

endpoints:
  curl:
    plugin: subproc
    config:
      prog: curl
      argfiles:
        - arg: '--key'
          filepath: /tmp/private_key
        - arg: '-d@'
          filepath: /tmp/data
      disallow-argfiles: true

Use section env to define environment variables always present:

endpoints:
  curl:
    plugin: subproc
    config:
      prog: curl
      env:
        HTTP_PROXY: http://proxy.example.com:3128/
        HTTPS_PROXY: http://proxy.example.com:3128/

Use section envfiles to define environment variables files always present:

endpoints:
  curl:
    plugin: subproc
    config:
      prog: curl
      envfiles:
        - somedir/foo.env
        - somedir/bar.env

Use keyword disallow-env to disable environment variables from client:

endpoints:
  curl:
    plugin: subproc
    config:
      prog: curl
      env:
        HTTP_PROXY: http://proxy.example.com:3128/
        HTTPS_PROXY: http://proxy.example.com:3128/
      disallow-env: true

Predefined AUTON environment variables during execution:

Variable Description
AUTON Mark the job is executed in AUTON environment
AUTON_JOB_TIME Current time in local time zone
AUTON_JOB_GMTIME Current time in GMT
AUTON_JOB_UID Current job uid passed from client
AUTON_JOB_UUID Unique ID of the current job

Auton command-lines

endpoint curl examples:

Get URL https://example.com:

auton --endpoint curl --uri http://localhost:8666 -a 'https://example.com'

Get URL https://example.com with auton authentication:

auton --endpoint curl --uri http://localhost:8666 --auth-user foo --auth-passwd bar -a 'https://example.com'

Add environment variable HTTP_PROXY:

auton --endpoint curl --uri http://localhost:8666 -a 'https://example.com' -e 'HTTP_PROXY=http://proxy.example.com:3128/'

Load environment variables from local files:

auton --endpoint curl --uri http://localhost:8666 -a 'https://example.com' --load-envfile foo.env

Tell to autond to load environment variables files from its local fs:

auton --endpoint curl --uri http://localhost:8666 -a 'https://example.com' --envfile /etc/auton/auton.env

Add multiple autond URIs for high availability:

auton --endpoint curl --uri http://localhost:8666 --uri http://localhost:8667 -a 'https://example.com'

Add arguments files to send local files:

auton --endpoint curl --uri http://localhost:8666 -A '--cacert=cacert.pem' -a 'https://example.com'

Add multiple arguments:

auton --endpoint curl --uri http://localhost:8666 --multi-args '-vvv -u foo:bar https://example.com' --multi-argsfiles '-d@=foo.txt -d@=bar.txt --cacert=cacert.pem'

Get file contents from stdin with -:

cat foo.txt | auton --endpoint curl --uri http://localhost:8666 --multi-args '-vvv -u foo:bar sftp://example.com' --multi-argsfiles '--key=private_key.pem --pubkey=public_key.pem -T=-'
