使用 Logspout 收集所有容器的
·
1.将所有容器的输出路由到远程 rsyslog 服务器
1.修改 rsyslog 配置文件/etc/rsyslog.conf, 从中找到 “# Provides UDP sysilog recepion"语句。并将该处的以下两行配置代码行首的“#”字符删除（取消注释）
[root@host1 ~]# vi /etc/rsyslog.conf
[root@host1 ~]# cat /etc/rsyslog.conf
# rsyslog configuration file
# For more information see /usr/share/doc/rsyslog-*/rsyslog_conf.html
# or latest version online at http://www.rsyslog.com/doc/rsyslog_conf.html
# If you experience problems, see http://www.rsyslog.com/doc/troubleshoot.html
#### GLOBAL DIRECTIVES ####
# Where to place auxiliary files
global(workDirectory="/var/lib/rsyslog")
# Use default timestamp format
module(load="builtin:omfile" Template="RSYSLOG_TraditionalFileFormat")
#### MODULES ####
module(load="imuxsock" # provides support for local system logging (e.g. via logger command)
SysSock.Use="off") # Turn off message reception via local log socket;
# local messages are retrieved through imjournal now.
module(load="imjournal" # provides access to the systemd journal
UsePid="system" # PID nummber is retrieved as the ID of the process the journal entry originates from
FileCreateMode="0644" # Set the access permissions for the state file
StateFile="imjournal.state") # File to store the position in the journal
#module(load="imklog") # reads kernel messages (the same are read from journald)
#module(load="immark") # provides --MARK-- message capability
# Include all config files in /etc/rsyslog.d/
include(file="/etc/rsyslog.d/*.conf" mode="optional")
# Provides UDP syslog reception
# for parameters see http://www.rsyslog.com/doc/imudp.html
module(load="imudp") # needs to be done just once
input(type="imudp" port="514")
# Provides TCP syslog reception
# for parameters see http://www.rsyslog.com/doc/imtcp.html
#module(load="imtcp") # needs to be done just once
#input(type="imtcp" port="514")
#### RULES ####
# Log all kernel messages to the console.
# Logging much else clutters up the screen.
#kern.* /dev/console
# Log anything (except mail) of level info or higher.
# Don't log private authentication messages!
*.info;mail.none;authpriv.none;cron.none /var/log/messages
# The authpriv file has restricted access.
authpriv.* /var/log/secure
# Log all the mail messages in one place.
mail.* -/var/log/maillog
# Log cron stuff
cron.* /var/log/cron
# Everybody gets emergency messages
*.emerg :omusrmsg:*
# Save news errors of level crit and higher in a special file.
uucp,news.crit /var/log/spooler
# Save boot messages also to boot.log
local7.* /var/log/boot.log
# ### sample forwarding rule ###
#action(type="omfwd"
# # An on-disk queue is created for this action. If the remote host is
# # down, messages are spooled to disk and sent when it is up again.
#queue.filename="fwdRule1" # unique name prefix for spool files
#queue.maxdiskspace="1g" # 1gb space limit (use as much as possible)
#queue.saveonshutdown="on" # save messages to disk on shutdown
#queue.type="LinkedList" # run asynchronously
#action.resumeRetryCount="-1" # infinite retries if host is down
# # Remote Logging (we use TCP for reliable delivery)
# # remote_host is: name/ip, e.g. 192.168.0.1, port optional e.g. 10514
#Target="remote_host" Port="XXX" Protocol="tcp")
2.保存该配置文件，执行 systemctl restart rsyslog 命令重启 rsyslog, 然后检查514端口是否
已开启
[root@host1 ~]# systemctl restart rsyslog
[root@host1 ~]# netstat -antup | grep 514
udp 0 0 0.0.0.0:514 0.0.0.0:* 418069/rsyslogd
udp6 0 0 :::514 :::* 418069/rsyslogd
3.启动Logspout 容器，将日志转发到 Docker 主机上的syslog日志系统中
[root@host1 ~]# docker run --rm --name="logspout" --volume=/var/run/docker.sock:/var/run/docker.sock
gliderlabs/logspout syslog+udp://192.168.197.9:514

接下来进行实际测试。
4.打开另一个终端窗口（或者标签页，下同)，执行tail-f/var/log/messages 命令使用 tail 工具实时监控系统日志文件/var/og/messages
[root@host1 ~]# tail -f /var/log/messages

5.再打开另一个终端窗口，执行以下命令启动一个Redis 容器
[root@host1 ~]# docker run --rm -d --name redis redis
638a1d615856362d3315b99e3d55d31ff8ac821376925c46ed88c8957fabd4b6
6.回到 tail 工具监控窗口，会发现该窗口显示了该容器输出的日志信息
Sep 16 17:04:56 host1 systemd[1]: Started libcontainer container 638a1d615856362d3315b99e3d55d31ff8ac821376925c46ed88c8957fabd4b6.

7.切换到另一个终端窗口，使用 docker logs 命令获取 Redis 容器的日志信息，会发现获取的日志信息与Logspout 容器收集到的完全一致
[root@host1 ~]# docker logs redis

1:C 16 Sep 2025 09:04:57.222 # WARNING Memory overcommit must be enabled! Without it, a background save or replication may fail under low memory condition. Being disabled, it can also cause failures without low memory condition, see https://github.com/jemalloc/jemalloc/issues/1328. To fix this issue add 'vm.overcommit_memory = 1' to /etc/sysctl.conf and then reboot or run the command 'sysctl vm.overcommit_memory=1' for this to take effect.

8.实验完毕，停止 Redis 容器和 Logspout 容器（切换该容器运行的终端窗口，按CultC组合键），它们会被自动删除。
[root@host1 ~]# docker stop redis

[root@host1 ~]# docker stop logspout
Error response from daemon: No such container: logspout

2.通过 HTTP 查看 Logspout 收集的日志
1.只需读取 HTTP数据流，即可实时查看生成的聚合日志。可以使用 Logspout 的 HTTP流模块，实时查看由它聚合的本地日志，而不用提供日志路由的URI，如执行以下操作：
[root@host1 ~]# docker run --rm -d --name="logspout" \
--volume /var/run/docker.sock:/var/run/docker.sock \
--publish=127.0.0.1:8000:80 \
gliderlabs/logspout
cfd9130ed802c6d28dd2e67f85899510016d9f423586802bc6a6d447bd727e4a
2.使用 curl 观察容器的日志流
[root@host1 ~]# curl http://127.0.0.1:8000/logs
3.打开另一个终端窗口，执行容器操作。这里启动 Redis 容器，切回前面的终端窗口，会发现关于 Redis 容器启动的日志流，如下所示
[root@host1 ~]# curl http://127.0.0.1:8000/logs
