卷和綁定座默認情況下裝入容器的文件系統(tǒng)，它們的內(nèi)容存儲在主機上。
在某些情況下，您可能不希望將容器的數(shù)據(jù)存儲在主機上，但也不希望將數(shù)據(jù)寫入容器的可寫層，原因是性能或安全原因，或者數(shù)據(jù)與非持久性應(yīng)用程序狀態(tài)有關(guān)。一個例子可能是容器的應(yīng)用程序創(chuàng)建并根據(jù)需要使用的臨時一次性密碼。
為了讓容器訪問數(shù)據(jù)而不需要永久寫入數(shù)據(jù)，可以使用tmpfs只存儲在主機內(nèi)存中的掛載（如果內(nèi)存不足，則使用交換）。當(dāng)容器停止時，tmpfs安裝座被移除。如果容器已提交，tmpfs則不會保存安裝。
選擇-tmpfs或-掛載標志。
最初，--tmpfs標志用于獨立容器，--mount旗號用于群服務(wù)。但是，從Docker 17.06開始，您還可以使用--mount用獨立的容器?？偟膩碚f，--mount更明確更詳細。最大的區(qū)別是--tmpfs標志不支持任何可配置選項。
針尖新用戶應(yīng)使用
--mount語法。有經(jīng)驗的用戶可能更熟悉--tmpfs語法，但鼓勵使用--mount因為研究表明它更容易使用。
--tmpfstmpfs安裝時不允許您指定任何可配置選項，并且只能與獨立容器一起使用。
--mount*由多個鍵值對組成，以逗號分隔，每個鍵值由一個<key>=<value>元組。大--mount語法比-v或--volume，但是鍵的順序并不重要，并且標志的值更容易理解。
- The `type` of the mount, which can be [`bind`](../bind-mounts-md/index), `volume`, or [`tmpfs`](index). This topic discusses `tmpfs`, so the type will always be `tmpfs`.- The `destination` takes as its value the path where the `tmpfs` mount will be mounted in the container. May be specified as `destination`, `dst`, or `target`.- The `tmpfs-type` and `tmpfs-mode` options. See [tmpfs options](about:blank#tmpfs-options).
下面的示例顯示了--mount和--tmpfs在可能的情況下語法，以及--mount首先介紹。
差異--tmpfs和--mount行為
大
--tmpfs標志不允許您指定任何可配置選項。
大
--tmpfs標記不能與群集服務(wù)一起使用。你必須用--mount...
tmpfs容器的限制
tmpfs容器之間不能共享掛載。
tmpfs掛載只在Linux容器上工作，而不是在Windows容器上工作。
在容器中使用tmpfs掛載
使用tmpfs安裝在容器中，使用--tmpfs標志，或使用--mount旗子type=tmpfs和destination選擇。沒有source為tmpfs坐騎。下面的示例創(chuàng)建tmpfs山/app在Nginx容器里。第一個示例使用--mount標志和第二個使用--tmpfs旗子。
--mount
--tmpfs
$ docker run -d \ -it \ --name tmptest \ --mount type=tmpfs,destination=/app \ nginx:latest
$ docker run -d \ -it \ --name tmptest \ --tmpfs /app \ nginx:latest
驗證掛載是否為tmpfs跑上山docker container inspect tmptest尋找Mounts部分：
"Tmpfs": { "/app": ""},拆下容器：
$ docker container stop tmptest $ Docker container rm tmptest
指定tmpfs選項
tmpfs掛載允許兩個配置選項，這兩個選項都不是必需的。如果需要指定這些選項，則必須使用--mount旗幟，如--tmpfs旗子不支持他們。
選項 | 描述 |
|---|---|
tmpfs的大小 | tmpfs的大小，以字節(jié)為單位。無限制默認。 |
tmpfs的模式 | tmpfs的八進制文件模式。例如，700或0770.默認為1777或世界可寫。 |
下面的示例設(shè)置tmpfs-mode到1770，因此在容器中它是不可讀的。
docker run -d \ -it \ --name tmptest \ --mount type=tmpfs,destination=/app,tmpfs-mode=1770 \ nginx:latest
