Initialize Dapr in your local environment

Dapr の初期化をします。
docker を使うのでDocker Desktopなどデーモンが起動していないとダメみたいです。

Step 2: Run the init CLI command

$ dapr init
⌛  Making the jump to hyperspace...
ℹ️  Container images will be pulled from Docker Hub
ℹ️  Installing runtime version 1.12.2
↙  Downloading binaries and setting up components...
Dapr runtime installed to /home/user/.dapr/bin, you may run the following to add it to your path if you want to run daprd directly:
    export PATH=$PATH:/home/user/.dapr/bin
✅  Downloading binaries and setting up components...
✅  Downloaded binaries and completed components set up.
ℹ️  daprd binary has been installed to /home/user/.dapr/bin.
ℹ️  dapr_placement container is running.
ℹ️  dapr_redis container is running.
ℹ️  dapr_zipkin container is running.
ℹ️  Use `docker ps` to check running containers.
✅  Success! Dapr is up and running. To get started, go here: https://aka.ms/dapr-getting-started

Step 3: Verify Dapr version

$ dapr --version
CLI version: 1.12.0
Runtime version: 1.12.2

Step 4: Verify containers are running

dapr の docker がいろいろ作られてます。dapr/zipkin/redisのイメージが作られるようです。

$ docker ps
CONTAINER ID   IMAGE                                 COMMAND                  CREATED         STATUS                   PORTS                                                                                                                                  NAMES

Step 5: Verify components directory has been initialized

$HOME/.dapr/ に何やらいろいろできるみたいなので覗いてみます。

$ ls -ltr $HOME/.dapr/
total 12
-rw-r--r-- 1 user user  187 Nov 29 15:24 config.yaml
drwxrwxrwx 2 user user 4096 Nov 29 15:24 components
drwxrwxrwx 3 user user 4096 Nov 29 15:24 bin
user@dpkatoy:~$ ls -ltr $HOME/.dapr/components
total 8
-rw-r--r-- 1 user user 254 Nov 29 15:24 statestore.yaml
-rw-r--r-- 1 user user 207 Nov 29 15:24 pubsub.yaml
$ ls -ltr $HOME/.dapr/bin

ふむ🤔見てもよくわからないので、次に行きましょう。笑

簡単でした👻
次はチュートリアルするよー
