Ansible deploy fails at "Run post_build_commands in the new_release_path"

Hi!

My ansible deploy fails at the composer install task:

TASK: [deploy | Run post_build_commands in the new_release_path] **************
failed: [preview.domain.tld] => (item={'cmd': 'composer install --no-ansi --no-dev --no-interaction --no-progress --optimize-autoloader --no-scripts'}) => {"cmd": "composer install --no-ansi --no-dev --no-interaction --no-progress --optimize-autoloader --no-scripts", "failed": true, "item": {"cmd": "composer install --no-ansi --no-dev --no-interaction --no-progress --optimize-autoloader --no-scripts"}, "rc": 2}
msg: [Errno 2] No such file or directory

FATAL: all hosts have already failed -- aborting

If I run this command (composer install --no-ansi --no-dev --no-interaction --no-progress --optimize-autoloader --no-scripts) manually (via ssh) in the new_release_path it works and composer installs all the necessary dependencies.

This staging server is on a shared hosting with ssh access.

And here is the group_vars/staging file (without the env part):

wordpress_sites:
  preview.domain.tld:
site_hosts:
  - preview.domain.tld
local_path: '../site'
repo: git@domain.tld:git/repo.git
branch: master
subtree: site
multisite:
  enabled: false
  subdomains: false
ssl:
  enabled: false
system_cron: true

I think it’s worth mentioning that the file structure in the new_release_path looks like this:

Any help is appreciated!

Can you post your full deploy log?

Yes, sure.

For your information: I never ran ansible-playbook -i hosts/staging server.yml because it is a shared hosting.

Thanks!

Did you make changes for that deploy run? Because it skipped post_build_commands instead of failing.

Only reason it would skip is you removed that composer task from the variable.

Unrelated: but you should add this line: https://github.com/roots/roots-example-project.com/blob/06c7f6abf84d58babaeef6a583469611cdd9b6ac/ansible/group_vars/all#L15

Yes, I’m sorry, should’ve mention that.

I made these changes to ansible/roles/deploy/defaults/main.yml for the deploy to complete successfully:

project_post_build_commands: []
# - cmd: "composer install --no-ansi --no-dev --no-interaction --no-progress --optimize-autoloader --no-scripts"

# Post finalize commands are run with Ansible's `shell` module.
# These are meant primarily for service restarts such as php5-fpm or memcached.
project_post_finalize_commands: []
#  - sudo service php5-fpm reload

I executed the composer command manually (working) and the second commented out line won’t work because of sudo/shared hosting.

A deploy with project_post_build_commands enabled looks like this:

Thanks for the project_unwanted_items!
Shouldn’t that be in https://github.com/roots/bedrock-ansible/blob/master/group_vars/all as well?
Or is it just because my git repo includes the whole project folder (ansible and site), like subtree: site?

I just realized that overwriting the values in roles/deploy/defaults/main.yml may not be the best practice and put all the configuration in group_vars/<staging/production>.

I tinkered around with some commands, the only one I got to work (and could check) was touch filename.
As soon as I switch to a command like wp or composer the error message appears:

msg: [Errno 2] No such file or directory

Seeeeeeems to be a shared hosting thing.
If I change the command from

`composer install --no-ansi --no-dev --no-interaction --no-progress --optimize-autoloader --no-scripts``

to

php ~/bin/composer install --no-ansi --no-dev --no-interaction --no-progress --optimize-autoloader --no-scripts

it works flawlessly.

Does anyone know why I have to specify the composer path?

When I execute which composer via SSH it prints the correct path to composer.

Tools like Ansible and Capistrano that issue SSH commands do so “non-interactively”. Here’s a good resource on this and the answer to your question: http://capistranorb.com/documentation/faq/why-does-something-work-in-my-ssh-session-but-not-in-capistrano/

Good job debugging :thumbsup:

This is great, thank you! It makes sense now.

I’m still trying to get the whole picture – but it gets clearer.

(As far as I’m concerned this topic can be closed.)
