2.11 test

2.12 write a startup script (tamping start command at the last start)

Vi init.shrunken daemon off;'~ Binram bashservice service-g 'daemon off;'~

2.13 generate an image

[root@docker03 / etc/nginx] # docker commit 274ca61dd89f docker_kod:v1sha256:da72ea94c8cbf9f2c21b7655b4146b0308053c3988fc2b6d165a1f6dd4cbc8de

3.docker manually creates images (based on C7) (Nginx+ssh)

3.1. Create and enter the container

[root@docker03 ~] # docker run-it-p 83:80 centos:7 [root@c919e69954a2 /] #

3.2. Change the Yum source and epel source of the container system

[root@c919e69954a2 /] # curl-o / etc/yum.repos.d/CentOS-Base.repo http://mirrors.aliyun.com/repo/Centos-7.repo% Total% Received% Xferd Average Speed Time Current Dload Upload Total Spent Left Speed 0000000000 -:: -0curl-o / etc/yum.repos.d/epel.repo http://mirrors.aliyun.com/repo/epel-7.repo100 2523 2523 00 17831 0--:-17893 [root@c919e69954a2 /] # curl-o / etc/yum.repos.d/epel.repo http://mirrors.aliyun.com/repo/epel- 7.repo% Total% Received% Xferd Average Speed Time Current Dload Upload Total Spent Left Speed100 664 100 664 00 5044 0 -:-5068

3.3. Install nginx

[root@c919e69954a2 /] # yum install nginx-y

3.4. Start the service

Note: C7 cannot start the service using systemctl in the container because the bus process is not started, and C7 starts fast because multiple processes start at the same time.

Root@docker03 ~] # ps-ef | grep busdbus 6819 10 Dec12? 00:00:03 / usr/bin/dbus-daemon-- system-- address=systemd:-- nofork-- nopidfile-- systemd-activationroot 43281 40267 0 11:09 pts/1 00:00:00 grep-- color=auto bus [root@c919e69954a2 /] # systemctl start nginxFailed to get D-Bus connection: Operation not permitted

Start the service manually

3.5. Install the ssh service

[root@c919e69954a2 /] # yum install openssh-server-y

3.6 start the sshd-keygen service (error because there is no key pair)

[root@c919e69954a2 /] # / usr/sbin/sshd-keygen/usr/sbin/sshd-keygen: line 10: / etc/rc.d/init.d/functions: No such file or directoryGenerating SSH2 RSA host key: / usr/sbin/sshd-keygen: line 63: success: command not foundGenerating SSH2 ECDSA host key: / usr/sbin/sshd-keygen: line 105: success: command not foundGenerating SSH2 ED25519 host key: / usr/sbin/sshd-keygen: line 126: success: command not found

3.7 query the corresponding software package in the host

[root@docker01] # rpm-qf / etc/rc.d/init.d/functionsinitscripts-9.49.46-1.el7.x86_64

3.8 install the package

[root@c919e69954a2 /] # yum install initscripts-y

3.9 check the key pair when starting the sshd-keygen service

[root@c1e50af6f42c /] # / usr/sbin/sshd-keygenGenerating SSH2 RSA host key: [OK] Generating SSH2 ECDSA host key: [OK] Generating SSH2 ED25519 host key: [OK] [root@c919e69954a2 /] # ls / etc/ssh/moduli ssh_host_ecdsa_key .pub ssh_host_ed25519_key.pub ssh_host_rsa_key.pub ssh_host_ecdsa_key ssh_host_ed25519_key ssh_host_rsa_key sshd_config

3.10 start the sshd service

[root@c919e69954a2 /] # systemctl cat sshd# / usr/lib/systemd/system/ SSH. Service [Description=OpenSSH server daemonDocumentation=man:sshd] man:sshd_config (5) After=network.target sshd-keygen.serviceWants=sshd- keygen.service [service] Type=notifyEnvironmentFile=/etc/sysconfig/sshdExecStart=/usr/sbin/sshd-D $OPTIONSExecReload=/bin/kill-HUP $MAINPIDKillMode=processRestart=on-failureRestartSec=42s [Install] WantedBy=multi-user.target [root@c919e69954a2 /] # / usr/sbin/sshd-D

3.11 set the container login password
