Following the example from Discourse-doctor 👩⚕️, I’ve created discourse-doctor, now included in discourse_docker. If you run ./discourse-doctor, you’ll see something like:

The output of this program may be available at http://twonames.ltcmp.net/YzUwYjE5MzlmN2EyZTAz.txt
You should inspect that file carefully before sharing the URL.
You can examine the output of this script with
LESS=-Ri less /tmp/discourse-debug.txt
BUT FIRST, make sure that you know the first three commands below!!!
Commands to know when viewing the file with the above command (called 'less'):
q -- quit
/error<ENTER> -- search for the word 'error'
n -- search for the next occurrence
g -- go to the beginning of the file
f -- go forward a page
b -- go back a page
G -- go to the end of the file
If the container isn’t running, discourse-doctor will attempt a rebuild and add the output of the build to the log file, which, if the container cranks up enough to have nginx, will be accessible via a URL, saving folks the trouble of uploading to something like pastebin. Passwords and email addresses are redacted by the script. Domain names are left intact, as there is rarely reason to hide your site given that it’s on the Internet already.
Right now, you have to know that discourse-doctor exists, but in the next few days, I’ll submit a PR to have launcher and discourse-setup recommend it.
Next Steps
- have launcher recommend
discourse-doctor - have discourse-setup recommend
discourse-doctor - make the mail test rake task do some actual testing rather than just sending , like . . .
– test connectivity to the port
– does password work
– SPF, DKIM, dmarc
– tell them they can’t use gmail (should also add this todiscourse-setup)
– tell them what email address is in the from: line - have
launcherdisallow mixed case domain names - if rebuild rails, re-start old container – this is both trivial and huge, as I think few people know that if the rebulid fails you can just restart the container.
- (tentative) do some kind of yml linting. It looks like
launcherdoes some kind ofyamlparsing inhost_run. But part of me says “You break it. You bought it.” - consider handling files other than
app.yml - have the doctor comment out plugins not from discourse github organization
If you have comments or suggestions, please let me know!
幸运的是，我目前只是用这台机器进行学习，所以没有造成任何损害。或许在继续之前，应该先询问用户是否希望执行如此重大的操作。
