docker启动容器

一般容器启动正常

portainer：似乎架构不兼容无法运行？docker logs查看

writing syncT "procError": write pipe: file already closed
libcontainer: container start initialization failed: exec /portainer: exec format errorlibcontainer: container init failed to exec

docker基本功能

支持新建docker网络

[root@localhost ~]# docker network create test-network

新建网络，新建两个容器在同一网络，可以ping通

备份镜像

[root@localhost ~]# docker images

docker稳定性

支持宿主机和docker容器同时压力测试

docker镜像为ubuntu:latest
ltp测试集在宿主机上通过git源码编译，安装到/opt/ltp目录下，详见https://linux-test-project.readthedocs.io/en/latest/users/quick_start.html
通过docker cp传入ubuntu镜像

#!/bin/bash

cd /opt/ltp && ./runltp mm &
docker exec  -w /opt/ltp ubuntu01 ./runltp mm &
