Il registro privato ha funzionato bene sulla base della finestra mobile 1.10.3, ma non è possibile eseguire il pull / push delle immagini dopo l'aggiornamento della finestra mobile alla 1.12.0.
Avevo modificato / etc / sysconfig / docker come:
OPTIONS='--selinux-enabled=true --insecure-registry=myip:5000'
o
OPTIONS='--selinux-enabled=true --insecure-registry myip:5000'
ma quando eseguo pull / push, ho ricevuto questo errore:
$ docker pull myip:5000/cadvisor
Using default tag: latest
Error response from daemon: Get https://myip:5000/v1/_ping: http: server gave HTTP response to HTTPS client
quando cambio la finestra mobile di nuovo in 1.10.3, funziona ancora bene come di seguito:
$ docker pull myip:5000/cadvisor
Using default tag: latest
Trying to pull repository myip:5000/cadvisor ...

Dopo aver riavviato il daemon docker in modalità debug, i registri del daemon durante la riproduzione del mio problema sono elencati di seguito:

Inoltre, eseguo un semplice comando per avviare il registro privato per il test, qualsiasi altra cosa è predefinita:
docker run -d -p 5000:5000 --restart=always --name registry -v 'pwd'/data:/var/lib/registry registry:2
Nessun proxy è configurato. In sintesi, è solo un ambiente di esempio silenzioso per il test.
