When none of a container&#8217;s networks can provide external connectivity, Docker connects the container to the docker_gwbridge network in addition to the container&#8217;s other networks, so that the container can connect to external networks or other swarm nodes.<br \/>\nReference:<br \/>\n<a href=\"https:\/\/docs.docker.com\/engine\/userguide\/networking\/#the-docker_gwbridge-network\" title=\"External link\" rel=\"nofollow noopener\" target=\"_blank\">https:\/\/docs.docker.com\/engine\/userguide\/networking\/#the-docker_gwb&#8230;<\/a><\/div>\n<p><\/strong><\/span> <\/div>\n","protected":false},"excerpt":{"rendered":"<p>What does the Docker network docker_gwbridge do?A. allows communication between containers on the same hostB. allows communication between swarm nodes on different hostsC. allows communication between swarm nodes on the same hostD. allows communication between containers on the different hosts Show Answer Hide Answer Correct Answer: B Explanation: Explanation: The docker_gwbridge is a local bridge [&hellip;]<\/p>\n","protected":false},"author":1,"featured_media":0,"comment_status":"closed","ping_status":"open","sticky":false,"template":"","format":"standard","meta":{"footnotes":""},"categories":[2],"tags":[3,492],"class_list":["post-501","post","type-post","status-publish","format-standard","hentry","category-aws-devops-engineer-professional-dop-c01","tag-aws-devops-engineer-professional-dop-c01","tag-question-489"],"_links":{"self":[{"href":"https:\/\/exampracticetests.com\/aws\/DevOps_Engineer_Professional_DOP-C01\/wp-json\/wp\/v2\/posts\/501","targetHints":{"allow":["GET"]}}],"collection":[{"href":"https:\/\/exampracticetests.com\/aws\/DevOps_Engineer_Professional_DOP-C01\/wp-json\/wp\/v2\/posts"}],"about":[{"href":"https:\/\/exampracticetests.com\/aws\/DevOps_Engineer_Professional_DOP-C01\/wp-json\/wp\/v2\/types\/post"}],"author":[{"embeddable":true,"href":"https:\/\/exampracticetests.com\/aws\/DevOps_Engineer_Professional_DOP-C01\/wp-json\/wp\/v2\/users\/1"}],"replies":[{"embeddable":true,"href":"https:\/\/exampracticetests.com\/aws\/DevOps_Engineer_Professional_DOP-C01\/wp-json\/wp\/v2\/comments?post=501"}],"version-history":[{"count":0,"href":"https:\/\/exampracticetests.com\/aws\/DevOps_Engineer_Professional_DOP-C01\/wp-json\/wp\/v2\/posts\/501\/revisions"}],"wp:attachment":[{"href":"https:\/\/exampracticetests.com\/aws\/DevOps_Engineer_Professional_DOP-C01\/wp-json\/wp\/v2\/media?parent=501"}],"wp:term":[{"taxonomy":"category","embeddable":true,"href":"https:\/\/exampracticetests.com\/aws\/DevOps_Engineer_Professional_DOP-C01\/wp-json\/wp\/v2\/categories?post=501"},{"taxonomy":"post_tag","embeddable":true,"href":"https:\/\/exampracticetests.com\/aws\/DevOps_Engineer_Professional_DOP-C01\/wp-json\/wp\/v2\/tags?post=501"}],"curies":[{"name":"wp","href":"https:\/\/api.w.org\/{rel}","templated":true}]}}
