* gcp(google cloud) centos 에 docker를 이용하여 tensorflow 설치

1 docker 설치
 이전 버전 삭제
 sudo yum remove docker \
                  docker-client \
                  docker-client-latest \
                  docker-common \
                  docker-latest \
                  docker-latest-logrotate \
                  docker-logrotate \
                  docker-selinux \
                  docker-engine-selinux \
                  docker-engine

 최신 저장소 설정
 sudo yum install -y yum-utils device-mapper-persistent-data lvm2
 sudo yum-config-manager --add-repo https://download.docker.com/linux/centos/docker-ce.repo

 최신 버전 설치
 yum install docker-ce
 
 Docker 서비스 등록 및 시작
 sudo systemctl enable docker
 sudo systemctl start docker
 
 ----- 여기 좀 애매함 ---
 도커 그룹 추가

#현재 접속중인 사용자에게 권한 주기

sudo usermod -aG docker $USER

#your-user 사용자에게 권한 주기

sudo usermod -aG docker your-user

2 tensorflow 설치
 - 책마다.... docker를 권장하는데 전부 제각각 버전을 사용한다.
   아무래도 책을 집필하시는 분들이 docker를 잘 모르는거 같다. ㅠ.ㅠ

 sudo docker search tensorflow
 sudo docker run -it -d --name "my-tensorflow" -p 8888:8888 -p 6006:6006 cargo.caicloud.io/tensorflow/tensorflow:1.0.0

 docker run -it -d --name "my-tensorflow" -p 8888:8888 -p 6006:6006 a0c164351caf
 my-tensorflow : 컨테이너명
 a0c164351caf : 이미지명
 호스트포트: 컨테이너포트
 
 docker start my-tensorflow
 docker ps -a
 docker attach my-tensorflow
 docker rm my-tensorflow

 docker run -it -d --name "my-tensorflow" 이미지명
 으로 실행하면 컨테이너가 실행 된다.
 실행중인 컨테이너에 접속하려면 attach로 접속이 안된다.
 이때는
 docker exec -it my-tensorflow /bin/bash를 실행하면 실행된다.
 컨테이너를 종료하지 않고 빠져 나오려면
 Ctrl + P를 누른다음 Ctrl + Q 를 실행하면 된다.

여기 내가 필요한 것을 잘 정리해 둔거 같다.

https://github.com/jonashackt/spring-boot-rest-clientcertificate/blob/master/src/test/java/de/jonashackt/RestClientCertTestConfiguration.java

private char[] allPassword = "allpassword".toCharArray();

    @Bean
    public RestTemplate restTemplate(RestTemplateBuilder builder) throws Exception {

        SSLContext sslContext = SSLContextBuilder
                .create()
                .loadKeyMaterial(ResourceUtils.getFile("classpath:keystore.jks"), allPassword, allPassword)
                .loadTrustMaterial(ResourceUtils.getFile("classpath:truststore.jks"), allPassword)
                .build();

        HttpClient client = HttpClients.custom()
                .setSSLContext(sslContext)
                .build();

        return builder
                .requestFactory(new HttpComponentsClientHttpRequestFactory(client))
                .build();
    }

키를 입력하지 않고 우회하는 방법은....

@Bean
    public RestTemplate restTemplate()
            throws KeyStoreException, NoSuchAlgorithmException, KeyManagementException {
        TrustStrategy acceptingTrustStrategy = (X509Certificate[] chain, String authType) -> true;
 
        SSLContext sslContext = org.apache.http.ssl.SSLContexts.custom()
                .loadTrustMaterial(null, acceptingTrustStrategy)
                .build();
 
        SSLConnectionSocketFactory csf = new SSLConnectionSocketFactory(sslContext);
 
        CloseableHttpClient httpClient = HttpClients.custom()
                .setSSLSocketFactory(csf)
                .build();
 
        HttpComponentsClientHttpRequestFactory requestFactory =
                new HttpComponentsClientHttpRequestFactory();
 
        requestFactory.setHttpClient(httpClient);
        RestTemplate restTemplate = new RestTemplate(requestFactory);
        return restTemplate;
    }
