[BUG] Docker-Compose shenyu services image not support arm64(Raspberry Pi 4 Model B) architecture

Is there an existing issue for this?

• I have searched the existing issues

Current Behavior

Docker-Compose file:

master/shenyu-dist/shenyu-docker-compose-dist/src/main/resources/stand-alone-mysql/docker-compose.yaml

shenyu-admin Docker file: master/shenyu-dist/shenyu-admin-dist/Dockerfile

shenyu-bootstrap Docker file: master/shenyu-dist/shenyu-bootstrap-dist/Dockerfile

I noticed that shenyu-admin and shenyu-bootstrap are both built on the openjdk:8-jre-alpine image, but this image does not support the arm64 CPU architecture of the Raspberry Pi 4 Model B, which prevents the shenyu services from running successfully.

The openjdk:8-jre-alpine image does not support the arm64 CPU architecture:

Expected Behavior

Make it work, thanks.

Steps To Reproduce

An error occurs after executing the following command:

curl https://raw.githubusercontent.com/apache/incubator-shenyu/master/shenyu-dist/shenyu-docker-compose-dist/src/main/resources/install.sh | bash -s master mysql

Environment

ShenYu version(s): 2.4.2

Anything else?

Using the arm64v8/openjdk:8-jre image in our project can run successfully(I’m actually using arm64v8/openjdk:8 😂).

Hi @myesn , I reproduced your problem locally 😃

I find that the base image you used openjdk:8u322-jre will make the env of spring invalid.

There may be no problem in the dockerfile, and it is recommended not to modify it. I read the log of your shenyu-bootstrap, that is probably because shenyu-admin failed to start successfully, not because of the image problem of openjdk.

@JooKS-me Thank you very much for your reply, I have compiled the following information for your reference.

All of the following steps are performed on the Raspberry Pi:

1. Download and extract v2.4.2 Souce code(tar.gz) 2. Open and edit the contents of incubator-shenyu-2.4.2/shenyu-dist/shenyu-admin-dist/Dockerfile and incubator-shenyu-2.4.2/shenyu-dist/shenyu-bootstrap-dist/Dockerfile files:

changes

# 1. Replace `FROM openjdk:8-jre-alpine` with:
FROM openjdk:8u322-jre

# 2. Replace `apk --no-cache add procps` with:
RUN apt-get update && \
    apt-get install -y --no-install-recommends procps && \
    rm -rf /var/lib/apt/lists/*

3. Switch to the incubator-shenyu-2.4.2/shenyu-dist directory and execute the following command (Total time 10:51 min):

mvn clean install -Dmaven.javadoc.skip=true -B -Drat.skip=true -Djacoco.skip=true -DskipITs -DskipTests -Prelease,docker

Although the following warning appears during the build process, the final result is BUILD SUCCESS:

4. Execute the following command to download the v2.4.2 install.sh file (auto-execute), the script will create a shenyu-v2.4.2 directory, since the database does not support arm64 architecture, this script will terminate when it outputs Pulling db(docker.io/mysql:5.7):

curl https://raw.githubusercontent.com/apache/incubator-shenyu/v2.4.2/shenyu-dist/shenyu-docker-compose-dist/src/main/resources/install.sh | bash -s v2.4.2 mysql

5. Open the shenyu-v2.4.2/docker-compose.yaml file and modify the following：

changes

1. Replace the `v2.4.2` tag character in the `image` value in the `shenyu-bootstrap` service with `2.4.2`
2. Replace the `v2.4.2` tag character in the `image` value in the `shenyu-admin` service with `2.4.2`
3. Add a new environment variable `shenyu.register.props.checked=false` to the `environment` of the `shenyu-admin` service
4. Replace the `image` value in the `db` service with `mariadb:10.2.41` ([[type: refactor] Change mysql image to mariadb in docker-compose yaml](https://github.com/apache/incubator-shenyu/pull/3210))

      retries: 10

6. Execute docker-compose up -d command to start the service collection, all 3 services are created and started successfully, then execute docker-compose logs -f shenyu-admin to view the logs:

shenyu-admin logs

From the logs, we can see that the shenyu-admin program is using the h2 profile, but the environment variable configured in docker-compose.yaml is mysql.

So I went inside the shenyu-admin container to check the environment variables and found no problems：

shenyu-admin environment variables inside the container

ubuntu@ubuntu:~/shenyu/docker/shenyu-v2.4.2$ docker-compose exec shenyu-admin bash
root@e289bd63ba2a:/opt/shenyu-admin# printenv
shenyu.register.props.checked=false
spring.profiles.active=mysql
spring.datasource.username=root
spring.datasource.url=jdbc:mysql://db:3306/shenyu?useUnicode=true&characterEncoding=utf-8&useSSL=false
spring.datasource.password=xyzj1a2y3
HOSTNAME=e289bd63ba2a
JAVA_HOME=/usr/local/openjdk-8

SHLVL=1
PATH=/usr/local/openjdk-8/bin:/usr/local/sbin:/usr/local/bin:/usr/sbin:/usr/bin:/sbin:/bin
JAVA_VERSION=8u322
_=/usr/bin/printenv

7. So I opened the docker-compose.yaml file and replaced spring.profiles.active=mysql with SPRING_PROFILES_ACTIVE=mysql in the environment of the shenyu-admin service:

      interval: 6s
      timeout: 5s
      retries: 10

8. Execute docker-compose down -v (for a clearer view of the logs), then execute docker-compose up -d again, wait for a successful start and then execute docker-compose logs -f shenyu-admin to view the logs:

shenyu-admin logs

From the output log, we can see that active profile is already correctly configured for mysql, but there is a Communications link failure error, which causes the program to run abnormally.

That’s all the steps and the process.
