Here are some useful things.

couchdb

couchdb-init.sh

This script can configure CouchDB with the necessary settings by REST APIs.

Materials

  • Mandatory: curl

Usage

export hostname=http://localhost:5984/
export username=couchdb-admin-username
export password=couchdb-admin-password
./couchdb-init.sh

curl result will be shown, however, all of them can be ignored if the script has been run completely.

fly.io

deploy-server.sh

A fully automated CouchDB deployment script. We can deploy CouchDB onto fly.io. The only we need is an account of it.

All omitted configurations will be determined at random. (And, it is preferred). The region is configured to nrt. If Japan is not close to you, please choose a region closer to you. However, the deployed database will work if you leave it at all.

Materials

  • Mandatory: curl, flyctl
  • Recommended: deno

Usage

#export appname=
#export username=
#export password=
#export database=
#export passphrase=
export region=nrt #pick your nearest location
./deploy-server.sh

The result of this command is as follows.

Your passphrase of Setup-URI is:  patient-haze
This passphrase is never shown again, so please note it in a safe place.

All we have to do is copy the setup-URI (obsidian://...`) and open it from Self-hosted LiveSync on Obsidian.

If you did not install Deno, configurations will be printed again, instead of the setup-URI. In this case, we should configure it manually.

delete-server.sh

The pair script of deploy-server.sh. We can delete the deployed server by this with fly.toml.

Materials

  • Mandatory: flyctl, jq
  • Recommended: none

Usage
