- there are 2 containers in docker compose:
    - jenkins
    - remote_host
- there are also 2 keys:
    - id_rsa
    - id_rsa3.pub
- when remote_host is building id_rsa3.pub is coping into: home/a12/.ssh/authorized_keys
- when I connect to jenkins container via:
    - docker exec -it jenkins bash
    and try:
    - ssh -i id_rsa3 a12@remote_host -> it can connect without password
- but when I configure same Jenkins SSH with this id_rsa3:
    - Can't connect to server

SSH was generate by: ssh-keygen -t rsa -m PEM -f id_rsa3
LOGS from Jenkins show -> Auth fail and Can't connect to server

我尝试：ssh-keygen -t rsa -m PEM -f id_rsa3而不是ssh-keygen -f id_rsa3。我尝试：重新启动Jenkins服务。我尝试：从Jenkins容器终端连接到remote_host（它正在工作）我尝试：在Jenkins中重新安装SSH。
