⌛ 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

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/
