mecab of 0.996
I will omit it because it only follows the "referenced article".
I didn't understand one point, or misunderstood, I thought that there was a setting to specify the endpoint somewhere when deploying locally or to heroku, so I searched variously.
I didn't write it anywhere, but somehow I came to a conclusion, so I wrote it so that I don't forget
Whether it's local or running on a server on the Internet, it connects to the Discord server and is recognized as online while client.run (TOKEN) is running and running. I think that's what it means.
I haven't read the source code and it's not reliable information, but I think that's probably the case.
Log in to heroku from the CLI.

If the deployment is successful, check the ** SCOPES ** on the OAuth2 page of the Discord developer page to access the URL displayed at the bottom and connect the bot to the server.
This should make the bot work (should).

Only the operating environment has changed, but it seems that the NEologd dictionary is used properly.
With this implementation, it will receive all the messages of the server to which the bot is connected and check if the mecab string exists (I think, maybe).
That is wasteful because it costs money to process most irrelevant messages.
If you implement the command, you will only be able to receive the message if the prefix and command strings are present (should, maybe).
discord_command_bot.py
import os
import MeCab
import discord
from discord.ext import commands
TOKEN = os.environ["TOKEN"]
bot = commands.Bot(command_prefix='!', description='Output to results of morphological analysis.')
@bot.event
async def on_ready():
print('Logged in as')
print(bot.user.name)
print(bot.user.id)
print('------')
@bot.command()
async def mecab(ctx, *args):
print("received message: " + str(args))
if bot.user != ctx.message.author:
l = list(args)
content = l.pop() #Treat the end as a character string to be parsed
print(content)
option = ' '.join(l)
mecab = MeCab.Tagger(option)
m = "```" + mecab.parse(content) + "```"
print(m)
#Send a message to the channel to which the message was sent
await ctx.send(m)
bot.run(TOKEN)
The difference from the non-command version is
client (discord.Client) is now bot (commands.Bot).mecab method.Rewrite the Dockerfile to execute with the command version.
CMD ["python", "discord_commmand_bot.py"]
Deploy to heroku.
heroku container:push web --app discord-bot-sample-app
heroku container:release web --app discord-bot-sample-app
The ! Mecab command should now be valid.

No reaction.
success.
It works as a bot for a few minutes after deploying, but soon goes offline. Also, if you deploy or turn dyno on / off, it will return, but I want to keep it running all the time.

When I looked it up, it seems that it was not good to push the container as web at the time of deployment.
heroku container:push web --app discord-bot-sample-app
heroku container:release web --app discord-bot-sample-app
Redeploy as worker.
heroku container:push worker --app discord-bot-sample-app
heroku container:release worker --app discord-bot-sample-app
Certainly this didn't stop.
