从我的本地计算机，我可以通过执行以下操作，无需密码即可 ssh 进入我的服务器：
ssh [email protected]
然后我检查/var/log/auth.log服务器以查看使用的 ssh 密钥。我得到这样的东西：
Feb 27 09:11:24 example sshd[1172697]: Accepted publickey for user1 from 146.70.115.169 port 36138 ssh2: RSA SHA256:Gf9ol8izys7sHnypV3jiLD4ftgjlknedb6zVi1EhYeY
Feb 27 09:11:24 example sshd[1172697]: pam_unix(sshd:session): session opened for user1 (uid=1000) by (uid=0)
然后我在本地计算机上运行以下命令来查找使用的 ssh 密钥文件：
find ~/.ssh -iname "*.pub" -print0 | xargs -r0 -I {} bash -c "readlink -f {}; ssh-keygen -l -f {}"
一旦我得到文件，我就会像这样编码：
base64 -w 0 < ~/.ssh/id_rsa > my_ssh_key
然后，我将编码后的密钥保存为 bitbucket 中的存储库变量。
然后，我创建一个在 bitbucket 管道上运行的脚本来部署我的项目：
我的bitbucket-pipelines.yml看起来像这样
image: php:8.1.13-alpine3.15
pipelines:
branches:
staging:
- step:
name: Deploy to Staging
deployment: staging
caches:
- composer
- npm
script:
- apk update && apk add --no-cache bash
- bash deploy.sh
部署脚本是这样的：
#!/usr/bin/env bash
set -ueo
echo "Build and deploy scripts"
apk update
apk add --no-cache openssh
apk add --update coreutils
echo "Deploy to test server"
mkdir -p ~/.ssh
cat known_hosts >> ~/.ssh/known_hosts
(umask 077 ; echo "${SSH_KEY}" | base64 --decode > ~/.ssh/id_rsa)
cat ~/.ssh/id_rsa
ssh -vvv "${SSH_USER}@${SSH_HOST}" "echo 'Connection successful'"
echo "Ready for testing!"
问题是我在管道上的 ssh 连接由于某种原因失败。

有人可以帮我解决这个问题吗？
谢谢
