无法验证 <ip-address> 的证书，因为它不包含任何 IP SAN

Question

我正在开发 GitLab CI 管道，它将部署我的 docker 堆栈。我正在尝试将 $DOCKER_HOST 设置为 tcp://DROPLET_IP:2377，但我收到一条错误消息，指出我的证书不包含任何 IP SAN。我正在使用 Digital Ocean Droplet 进行测试，所以我还没有为我的 Droplet 设置域名。

deploy:
  stage: deploy
  image: docker:stable
  services:
    - docker:dind
  variables:
    DOCKER_HOST: "tcp://$DROPLET_IP:2377"
    DOCKER_TLS_VERIFY: 1
  before_script:
    - mkdir -p ~/.docker
    - echo "$TLS_CA_CERT" > ~/.docker/ca.pem
    - echo "$TLS_CERT" > ~/.docker/cert.pem
    - echo "$TLS_KEY" > ~/.docker/key.pem
  script:
    - docker login -u gitlab-ci-token -p "$CI_JOB_TOKEN" "$CI_REGISTRY"
    - docker info
    - docker stack deploy --with-registry-auth --compose-file=docker-stack.yml mystack

这是我在 GitLab CI 作业的输出中遇到的错误：

$ docker login -u gitlab-ci-token -p "$CI_JOB_TOKEN" "$CI_REGISTRY"
WARNING! Using --password via the CLI is insecure. Use --password-stdin.
error during connect: Post https://<ip-address>:2377/v1.39/auth: x509: cannot validate certificate for <ip-address> because it doesn't contain any IP SANs

我正在使用以下一组命令生成我的证书（ca.pem、server-cert.pem 和 server-key.pem），我想在我的 [=18= 中使用它们]阶段如上所述。我已将 TLS_CA_CERT、TLS_CERT 和 TLS_KEY 保存到 GitLab CI 中使用的变量中。

openssl genrsa -aes256 -out ca-key.pem 4096

openssl req -new -x509 -days 365 -key ca-key.pem -sha256 -out ca.pem

openssl genrsa -out server-key.pem 4096

openssl req -subj "/CN=<ip-address>" -sha256 -new -key server-key.pem -out server.csr

echo subjectAltName = IP:<ip-address> >> extfile.cnf

echo extendedKeyUsage = serverAuth >> extfile.cnf

openssl x509 -req -days 365 -sha256 -in server.csr -CA ca.pem -CAkey ca-key.pem \
  -CAcreateserial -out server-cert.pem -extfile extfile.cnf

Answer 1

我看到您在 subjectAltName

中包含了 IP 地址

echo subjectAltName = IP:<ip-address> >> extfile.cnf

检查，as in here，如果这是配置问题：

I put subjectAltName in the wrong section. Working method: Basically I edited openssl.cnf, in section [v3_ca] I added 'subjectAltName = IP:192.168.2.107'.
Produced new certificate and added to server + client.

您需要确保您的扩展在 v3_ca 部分声明为 shown here.

Answer 2

从 OpenSSL 1.1.1 开始，直接在命令行上提供 subjectAltName 变得 容易得多 ，因为 -addext 标志被引入 openssl req

示例：

export HOST="my.host"
export IP="127.0.0.1"
openssl req -newkey rsa:4096 -nodes -keyout ${HOST}.key -x509 -days 365 -out ${HOST}.crt -addext 'subjectAltName = IP:${IP}' -subj '/C=US/ST=CA/L=SanFrancisco/O=MyCompany/OU=RND/CN=${HOST}/'
