<p><span class="autocomment">导入</span></p>
<p><b>新页面</b></p><div>==导出==<br />
docker export docker4wiki_mediawiki_1 >docker4wiki_mediawiki_1.tar<br />
<br />
docker export docker4wiki_database_1 >docker4wiki_database_1.tar<br />
<br />
==导入==<br />
<pre><br />
Import to docker via pipe and STDIN<br />
cat ./你的导出.tar | sudo docker import - 新的名字:1.0<br />
<br />
Import with a commit message<br />
$ cat exampleimage.tgz | docker import --message "New image imported from tarball" - exampleimagelocal:new<br />
<br />
#我的命令<br />
cat docker4wiki_database_1.tar | docker import --message "dbwiki" - imported:docker4wiki_database_1<br />

sudo docker images可以看到刚才导入的新镜像<br />

<br />
<br />
根据自己的需要开启容器<br />
<br />
docker run -dit -v /dep:/dep -p 80:80 -p 7000-7001:7000-7001 dockertest:1.0 /bin/bash<br />
<br />
-v 是docker目录挂载，冒号左边是本地目录，右边是docker内目录<br />
-p 是docker端口映射，冒号左边是本地端口，右边是docker内端口<br />
<br />
<br />
<br />
#我的命令<br />
具体的command需要在导出容器的时候通过docker ps查看到。 或者直接加 /bin/bash 应该也行<br />
ocker ps <br />

Question<br />
docker export : "fatal error: runtime: out of memory<br />
<br />
Solution<br />
[[Linux添加swap交换分区(虚拟内存)]]<br />
<br />
<br />
导入的错误 <br />
注意：运行导入的镜像的时候必须带command，否则启动报如下错误<br />
<br />
FATA[0000] Error response from daemon: No command specified <br />
<br />
具体的command需要在导出容器的时候通过docker ps查看到。<br />
