logback相關(guān)裝備，其間${LOG_HOME}表明為環(huán)境變量，在java發(fā)動(dòng)應(yīng)用程序時(shí)，經(jīng)過java-DLOG_HOME=”途徑”來指定的，能夠動(dòng)態(tài)去設(shè)置它的地址。

上面代碼中${LOG_HOME-/home}/logs表明，如果沒有傳入環(huán)境變量LOG_HOME，然后就使用后面的/home途徑，對(duì)于windows體系來說，/home表明當(dāng)時(shí)jar包地點(diǎn)的盤符。
項(xiàng)目發(fā)動(dòng)
java-Dlogback_home=”c:\\logs”-jareureka.jar
這樣就把日志文件存儲(chǔ)到了C盤logs目錄了。
docker容器時(shí)指定
