db:download task : Read-only file system

[tazeverywhere]

Hi @kszymukowicz,

I use deployer-extended-wp-composer with a roots-bedrock setup for all my wp projects and usually everything works nicely. Dev-env is powered by local app (localwp.com).

Recently, after an upgrade from deployer-extended-wordpress-composer v4.0 to v7.0, during process of dep db:pull production, I have now an error on the "db:download" step.

As I understand the error, the process failed during the dumps trying to create a dir on the remote server ("mkdir" see error output above) ?
I have a Read-only file system error.

But if I look at the dumps folder on the remote server, dumps are created.
If I try a db:backup task, everything works as well.

Everything work fine for deploy, but I can't find the problem with db:pull.

Cmd and error output are:

Any idea or advice ?

hi
look what changed in version 6.0.0
https://github.com/sourcebroker/deployer-extended-wordpress-composer/blob/master/CHANGELOG.rst

The config is now read from config/.env.
Did you modified your files for this?

Also try to run the command with -vvv. Maybe there will be more data to debug.

Could be that this folder is tried to be created locally because for some reason the instance name is wrongly read for local instance.

Hi,

Thanks for your answer!

Yes, .env is in config folder now as all other (breaking) changes after upgrade are made.

The only thing I see is that I needed to customize the instances names, because of your default changes, and re-set it with set('instance_...).
BUT, I also have a "staging/test" instance, and the only way I found to be regognized by deployer is fallback it to default_stage (see above). I don't think it's the right way and maybe it throw an error somewhere ?
(I didn't found a clue in your code :P )

namespace Deployer;

require __DIR__ . '/vendor/autoload.php';
new \SourceBroker\DeployerExtendedWordpressComposer\Loader();

set('instance_local_name', 'development');
set('instance_live_name', 'production');
set('default_stage', 'staging');

#(...)

If I run dep config:hosts it says

+-------------+-------------------------+-------------+-------+------------------------------------------+

Ok.

Thanks again for your time.

[kszymukowicz]

You should not touch set('default_stage' ..);
default_stage is set dynamically based on WP_ENV or WP_INSTANCE.

[kszymukowicz]

What is the behaviour when you remove set('default_stage', 'staging'); ?

[tazeverywhere]

Ok I didn't know that. So I removed the "set default_instance".
I have now a Hostname or stage "dev" not found. error (indeed, that's why I did the default_stage thing..), even with a dep deploy xxx.

if i add a WP_INSTANCE in .env, in addition of INSTANCE..
IT WORKS !! (same for production and staging)

INSTANCE='development'
WP_INSTANCE='development'

It's strange, because WP_ENV is already defined in .env (and works in Bedrock), and as I can see in EnvDriver.php, it should also works, no ?
